CVE-2025-55202 2 Apereo, Opencast 2 Opencast, Opencast 2025-09-03 5.3 Medium
Opencast is a free, open-source platform to support the management of educational audio and video content. In version 18.0 and versions before 17.7, the protections against path traversal attacks in the UI config module are insufficient, still partially allowing for attacks in very specific cases. The path is checked without checking for the file separator. This could allow attackers access to files within another folder which starts with the same path. This issue has been fixed in versions 17.7 and 18.1. To mitigate this issue, check for folders that start with the same path as the ui-config folder.
CVE-2025-54380 2 Apereo, Opencast 2 Opencast, Opencast 2025-08-26 6.5 Medium
Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to version 17.6, Opencast would incorrectly send the hashed global system account credentials (ie: org.opencastproject.security.digest.user and org.opencastproject.security.digest.pass) when attempting to fetch mediapackage elements included in a mediapackage XML file. A previous CVE prevented many cases where the credentials were inappropriately sent, but not all. Anyone with ingest permissions could cause Opencast to send its hashed global system account credentials to a url of their choosing. This issue is fixed in Opencast 17.6.
CVE-2024-52797 2 Apereo, Opencast 2 Opencast, Opencast 2025-08-26 6.5 Medium
Opencast is free and open source software for automated video capture and distribution. First noticed in Opencast 13 and 14, Opencast's Elasticsearch integration may generate syntactically invalid Elasticsearch queries in relation to previously acceptable search queries. From Opencast version 11.4 and newer, Elasticsearch queries are retried a configurable number of times in the case of error to handle temporary losses of connection to Elasticsearch. These invalid queries would fail, causing the retry mechanism to begin requerying with the same syntactically invalid query immediately, in an infinite loop. This causes a massive increase in log size which can in some cases cause a denial of service due to disk exhaustion. Opencast 13.10 and Opencast 14.3 contain patches which address the base issue, with Opencast 16.7 containing changes which harmonize the search behaviour between the admin UI and external API. Users are strongly recommended to upgrade as soon as possible if running versions prior to 13.10 or 14.3. While the relevant endpoints require (by default) `ROLE_ADMIN` or `ROLE_API_SERIES_VIEW`, the problem queries are otherwise innocuous. This issue could be easily triggered by normal administrative work on an affected Opencast system. Those who run a version newer than 13.10 and 14.3 and see different results when searching in their admin UI vs your external API or LMS, may resolve the issue by upgrading to 16.7. No known workarounds for the vulnerability are available.

CVE-2018-16153 1 Apereo 1 Opencast 2025-05-27 7.5 High
An issue was discovered in Apereo Opencast 4.x through 10.x before 10.6. It sends system digest credentials during authentication attempts to arbitrary external services in some situations.
CVE-2022-29237 1 Apereo 1 Opencast 2025-04-23 5.4 Medium
Opencast is a free and open source solution for automated video capture and distribution at scale. Prior to Opencast 10.14 and 11.7, users could pass along URLs for files belonging to organizations other than the user's own, which Opencast would then import into the current organization, bypassing organizational barriers. Attackers must have full access to Opencast's ingest REST interface, and also know internal links to resources in another organization of the same Opencast cluster. Users who do not run a multi-tenant cluster are not affected by this issue. This issue is fixed in Opencast 10.14 and 11.7.
CVE-2022-39369 2 Apereo, Fedoraproject 2 Phpcas, Fedora 2025-04-23 8 High
phpCAS is an authentication library that allows PHP applications to easily authenticate users via a Central Authentication Service (CAS) server. The phpCAS library uses HTTP headers to determine the service URL used to validate tickets. This allows an attacker to control the host header and use a valid ticket granted for any authorized service in the same SSO realm (CAS server) to authenticate to the service protected by phpCAS. Depending on the settings of the CAS server service registry in worst case this may be any other service URL (if the allowed URLs are configured to "^(https)://.*") or may be strictly limited to known and authorized services in the same SSO federation if proper URL service validation is applied. This vulnerability may allow an attacker to gain access to a victim's account on a vulnerable CASified service without victim's knowledge, when the victim visits attacker's website while being logged in to the same CAS server. phpCAS 1.6.0 is a major version upgrade that starts enforcing service URL discovery validation, because there is unfortunately no 100% safe default config to use in PHP. Starting this version, it is required to pass in an additional service base URL argument when constructing the client class. For more information, please refer to the upgrading doc. This vulnerability only impacts the CAS client that the phpCAS library protects against. The problematic service URL discovery behavior in phpCAS < 1.6.0 will only be disabled, and thus you are not impacted from it, if the phpCAS configuration has the following setup: 1. `phpCAS::setUrl()` is called (a reminder that you have to pass in the full URL of the current page, rather than your service base URL), and 2. `phpCAS::setCallbackURL()` is called, only when the proxy mode is enabled. 3. If your PHP's HTTP header input `X-Forwarded-Host`, `X-Forwarded-Server`, `Host`, `X-Forwarded-Proto`, `X-Forwarded-Protocol` is sanitized before reaching PHP (by a reverse proxy, for example), you will not be impacted by this vulnerability either. If your CAS server service registry is configured to only allow known and trusted service URLs the severity of the vulnerability is reduced substantially in its severity since an attacker must be in control of another authorized service. Otherwise, you should upgrade the library to get the safe service discovery behavior.
CVE-2022-41965 1 Apereo 1 Opencast 2025-04-23 5.7 Medium
Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to Opencast 12.5, Opencast's Paella authentication page could be used to redirect to an arbitrary URL for authenticated users. The vulnerability allows attackers to redirect users to sites outside of one's Opencast install, potentially facilitating phishing attacks or other security issues. This issue is fixed in Opencast 12.5 and newer.
CVE-2017-1000221 1 Apereo 1 Opencast 2025-04-20 N/A
In Opencast 2.2.3 and older if user names overlap, the Opencast search service used for publication to the media modules and players will handle the access control incorrectly so that users only need to match part of the user name used for the access restriction. For example, a user with the role ROLE_USER will have access to recordings published only for ROLE_USER_X.
CVE-2017-1000071 1 Apereo 1 Phpcas 2025-04-20 N/A
Jasig phpCAS version 1.3.4 is vulnerable to an authentication bypass in the validateCAS20 function when configured to authenticate against an old CAS server.
CVE-2012-5583 1 Apereo 1 Phpcas 2025-04-12 N/A
phpCAS before 1.3.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2015-1169 1 Apereo 1 Central Authentication Service 2025-04-12 N/A
Apereo Central Authentication Service (CAS) Server before 3.5.3 allows remote attackers to conduct LDAP injection attacks via a crafted username, as demonstrated by using a wildcard and a valid password to bypass LDAP authentication.
CVE-2010-3692 1 Apereo 1 Phpcas 2025-04-11 N/A
Directory traversal vulnerability in the callback function in client.php in phpCAS before 1.1.3, when proxy mode is enabled, allows remote attackers to create or overwrite arbitrary files via directory traversal sequences in a Proxy Granting Ticket IOU (PGTiou) parameter.
CVE-2010-3691 1 Apereo 1 Phpcas 2025-04-11 N/A
PGTStorage/pgt-file.php in phpCAS before 1.1.3, when proxy mode is enabled, allows local users to overwrite arbitrary files via a symlink attack on an unspecified file.
CVE-2010-3690 1 Apereo 1 Phpcas 2025-04-11 N/A
Multiple cross-site scripting (XSS) vulnerabilities in phpCAS before 1.1.3, when proxy mode is enabled, allow remote attackers to inject arbitrary web script or HTML via (1) a crafted Proxy Granting Ticket IOU (PGTiou) parameter to the callback function in client.php, (2) vectors involving functions that make getCallbackURL calls, or (3) vectors involving functions that make getURL calls.
CVE-2023-4612 1 Apereo 1 Central Authentication Service 2025-02-27 9.8 Critical
Improper Authentication vulnerability in Apereo CAS in jakarta.servlet.http.HttpServletRequest.getRemoteAddr method allows Multi-Factor Authentication bypass.This issue affects CAS: through 7.0.0-RC7. It is unknown whether in new versions the issue will be fixed. For the date of publication there is no patch, and the vendor does not treat it as a vulnerability.
CVE-2023-28857 1 Apereo 1 Central Authentication Service 2024-11-27 4 Medium
Apereo CAS is an open source multilingual single sign-on solution for the web. Apereo CAS can be configured to use authentication based on client X509 certificates. These certificates can be provided via TLS handshake or a special HTTP header, such as “ssl_client_cert”. When checking the validity of the provided client certificate, X509CredentialsAuthenticationHandler performs check that this certificate is not revoked. To do so, it fetches URLs provided in the “CRL Distribution Points” extension of the certificate, which are taken from the certificate itself and therefore can be controlled by a malicious user. If the CAS server is configured to use an LDAP server for x509 authentication with a password, for example by setting a “cas.authn.x509.ldap.ldap-url” and “cas.authn.x509.ldap.bind-credential” properties, X509CredentialsAuthenticationHandler fetches revocation URLs from the certificate, which can be LDAP urls. When making requests to this LDAP urls, Apereo CAS uses the same password as for initially configured LDAP server, which can lead to a password leak. An unauthenticated user can leak the password used to LDAP connection configured on server. This issue has been addressed in version 6.6.6. Users are advised to upgrade. There are no known workarounds for this vulnerability.
