CVE-2014-9377
HighSummary
A heap-based buffer overflow in the nbns_spoof function in Ettercap 0.8.1 can be exploited by remote attackers. Attackers can cause a denial of service or potentially execute arbitrary code by sending a large netbios packet.
Risk Assessment
The organization may be exposed to remote attacks that could lead to system crashes or unauthorized access. Exploitation of this vulnerability could result in serious data security consequences.
Recommendation
It is recommended to update to the latest version of Ettercap to mitigate this vulnerability. Additionally, monitoring network traffic for suspicious netbios packets is advisable.
Other vulnerabilities in Ettercap 0.8.1
See all- CVE-2014-9379High
The radius_get_attribute function in Ettercap 0.8.1 performs an incorrect cast, allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, leading to a stack-based buffer overflow.
- CVE-2014-9378High
Ettercap version 0.8.1 does not validate certain return values, allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted data passed to the parse_line or dissector_imap functions.
- CVE-2014-9376High
An 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. This can occur in several functions, including dissector_dhcp, dissector_gg, and dissector_TN3270.
- CVE-2014-6396High
The dissector_postgresql function in Ettercap before version 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-2017-8366Critical
The strescape function in ec_strings.c in Ettercap 0.8.2 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted filter that is mishandled by etterfilter.
- CVE-2026-9365Medium
In Ettercap up to version 0.8.3, a heap-based buffer overflow exists in the FUNC_DECODER function of the GG Dissector component (file ec_gg.c). Manipulation of the gg argument can lead to a remote attack, though exploitation is difficult.
Original NVD description (English source)
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.
