SIPp through 3.7.7 Buffer Overflow via Oversized SIP Header Content

SIPp through 3.7.7 contains a buffer overflow vulnerability in the get_header() function in src/sip_parser.cpp when processing SIP messages with header content exceeding 20,490 bytes. Unauthenticated remote attackers can send crafted SIP messages with oversized headers to overflow the static buffer and crash the process.

SIPp through 3.7.7 Buffer Overflow via SIP To Header Tag

SIPp through 3.7.7 contains a buffer overflow vulnerability in get_peer_tag() function when processing SIP To headers with tag parameters of 2049 bytes or more. Unauthenticated remote attackers can send crafted SIP messages with oversized tag parameters to overflow the static buffer and crash the process.

SIPp through 3.7.7 Stack Buffer Overflow via createAuthHeader Algorithm Parameter

SIPp through 3.7.7 contains a stack buffer overflow vulnerability in createAuthHeader() when processing SIP authentication challenges with oversized algorithm parameters. A malicious SIP server can send a crafted 401 or 407 challenge to corrupt the stack and crash the client process.

SIPp 3.6 Local Buffer Overflow via Command-line Arguments

SIPp 3.6 and earlier contains a local buffer overflow vulnerability in command-line argument handling that allows local attackers to crash the application or execute arbitrary code. Attackers can trigger the vulnerability by supplying oversized input to the -3pcc, -i, or -log_file parameters, causing strcpy to write beyond buffer boundaries in sipp.cpp.

Stack-based buffer overflow in the get_remote_video_port_media function in call.cpp in SIPp 3.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted SIP message. NOTE: some of these details are obtained from third party information.

Sipp/sipp: sipp: denial of service and potential arbitrary code execution vulnerability

A flaw was found in SIPp. A remote attacker could exploit this by sending specially crafted Session Initiation Protocol (SIP) messages during an active call. This vulnerability, a NULL pointer dereference, can cause the application to crash, leading to a denial of service. Under specific conditions, it may also allow an attacker to execute unauthorized code, compromising the system's integrity and availability.

SIPP 3.3 Stack-Based Buffer Overflow via Configuration File

SIPP 3.3 contains a stack-based buffer overflow vulnerability that allows local unauthenticated attackers to execute arbitrary code by supplying malicious input in the configuration file. Attackers can craft a configuration file with oversized values that overflow a stack buffer, overwriting the return address and executing arbitrary code through return-oriented programming gadgets.
