CVE-2026-125401 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.1 High
Ettercap through 0.8.4.1 contains a heap buffer overflow vulnerability in gg_get_version() in src/dissectors/ec_gg.c that writes up to 44 bytes into a 30-byte allocation. Remote attackers can send Gadu-Gadu traffic on TCP port 8074 with a crafted version field through a monitored network to corrupt heap memory in the Ettercap process, which normally runs as root.
CVE-2026-125400 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.8 High
Ettercap through 0.8.4.1 contains a use-after-free vulnerability in func_pcre() in src/ec_filter.c that reads the PCRE2 ovector after freeing match data. Network-adjacent attackers can send packets matching a loaded pcre_regex() substitution filter to corrupt memory and potentially execute code as root.
CVE-2026-125406 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 8.8 High
Ettercap through 0.8.4.1 contains a stack buffer underwrite vulnerability in the telnet dissector in src/dissectors/ec_telnet.c that decrements the output pointer on backspace without a lower bound check. Attackers can send a telnet stream with more backspaces than preceding characters to write below the stack buffer, corrupting the stack of the Ettercap process that normally runs as root.
CVE-2026-125404 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-11-10 7.5 High
Ettercap through 0.8.4.1 contains an integer underflow in ccmp_decrypt() in src/ec_encryption_ccmp.c that subtracts the 8-byte CCMP trailer without checking minimum length. Attackers on a network whose WPA key is loaded can send a short crafted CCMP frame to overflow a stack buffer in the Ettercap process, which normally runs as root.
CVE-2026-125405 1 Ettercap-project 1 Ettercap 2026-11-10 8.1 High
Ettercap through 0.8.4.1 contains an out-of-bounds read vulnerability in Parse_NTLM_Auth() in src/dissectors/ec_http.c due to unvalidated NTLM message offsets. Attackers can send a crafted HTTP Authorization header observed by Ettercap to read beyond the buffer, disclosing memory or crashing the process.
CVE-2026-125403 1 Ettercap-project 1 Ettercap 2026-11-10 8.1 High
Ettercap through 0.8.4.1 contains an out-of-bounds read and size_t underflow vulnerability in sslw_remove_sts() in src/ec_sslwrap.c, caused by a stale length and an unchecked memmem() result when stripping Strict-Transport-Security headers. A malicious HTTPS server whose response passes through Ettercap's SSL interception can trigger out-of-bounds reads and memory corruption in the Ettercap process, which normally runs as root.
CVE-2026-125402 1 Ettercap-project 1 Ettercap 2026-11-10 8.1 High
Ettercap through 0.8.4.1 contains a heap out-of-bounds read vulnerability in sslw_get_clienthello_sni() in src/ec_sslwrap.c that trusts the unchecked 16-bit SNI length field. Network-adjacent attackers can send crafted TLS ClientHello messages during SSL interception to leak up to 64 KB of heap memory upstream or crash Ettercap.
CVE-2026-3606 2 Ettercap, Ettercap-project 2 Ettercap, Ettercap 2026-04-16 3.3 Low
A vulnerability has been found in Ettercap 0.8.4-Garofalo. Affected by this vulnerability is the function add_data_segment of the file src/ettercap/utils/etterfilter/ef_output.c of the component etterfilter. The manipulation leads to out-of-bounds read. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2017-6430 1 Ettercap-project 1 Ettercap 2025-04-20 N/A
The compile_tree function in ef_compiler.c in the Etterfilter utility in Ettercap 0.8.2 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted filter.
CVE-2014-9381 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
Integer signedness error in the dissector_cvs function in dissectors/ec_cvs.c in Ettercap 0.8.1 allows remote attackers to cause a denial of service (crash) via a crafted password, which triggers a large memory allocation.
CVE-2014-9376 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
Integer underflow in Ettercap 0.8.1 allows remote attackers to cause a denial of service (out-of-bounds write) and possibly execute arbitrary code via a small (1) size variable value in the dissector_dhcp function in dissectors/ec_dhcp.c, (2) length value to the dissector_gg function in dissectors/ec_gg.c, or (3) string length to the get_decode_len function in ec_utils.c or a request without a (4) username or (5) password to the dissector_TN3270 function in dissectors/ec_TN3270.c.
CVE-2014-9377 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
Heap-based buffer overflow in the nbns_spoof function in plug-ins/nbns_spoof/nbns_spoof.c in Ettercap 0.8.1 allows remote attackers to cause a denial of service or possibly execute arbitrary code via a large netbios packet.
CVE-2014-6395 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
Heap-based buffer overflow in the dissector_postgresql function in dissectors/ec_postgresql.c in Ettercap before 0.8.1 allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted password length value that is inconsistent with the actual length of the password.
CVE-2014-6396 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
The dissector_postgresql function in dissectors/ec_postgresql.c in Ettercap before 0.8.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted password length, which triggers a 0 character to be written to an arbitrary memory location.
CVE-2014-9378 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
Ettercap 0.8.1 does not validate certain return values, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted (1) name to the parse_line function in mdns_spoof/mdns_spoof.c or (2) base64 encoded password to the dissector_imap function in dissectors/ec_imap.c.
CVE-2014-9379 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
The radius_get_attribute function in dissectors/ec_radius.c in Ettercap 0.8.1 performs an incorrect cast, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, which triggers a stack-based buffer overflow.
CVE-2014-9380 1 Ettercap-project 1 Ettercap 2025-04-12 N/A
The dissector_cvs function in dissectors/ec_cvs.c in Ettercap 0.8.1 allows remote attackers to cause a denial of service (out-of-bounds read) via a packet containing only a CVS_LOGIN signature.
CVE-2013-0722 1 Ettercap-project 1 Ettercap 2025-04-11 N/A
Stack-based buffer overflow in the scan_load_hosts function in ec_scan.c in Ettercap 0.7.5.1 and earlier might allow local users to gain privileges via a Trojan horse hosts list containing a long line.
CVE-2010-3844 2 Debian, Ettercap-project 2 Debian Linux, Ettercap 2024-11-21 8.8 High
An unchecked sscanf() call in ettercap before 0.7.5 allows an insecure temporary settings file to overflow a static-sized buffer on the stack.
CVE-2010-3843 1 Ettercap-project 1 Ettercap 2024-11-21 7.8 High
The GTK version of ettercap uses a global settings file at /tmp/.ettercap_gtk and does not verify ownership of this file. When parsing this file for settings in gtkui_conf_read() (src/interfacesgtk/ec_gtk_conf.c), an unchecked sscanf() call allows a maliciously placed settings file to overflow a statically-sized buffer on the stack.
