Detailsinfo

A vulnerability classified as critical has been found in SIPp up to 3.6. This affects an unknown functionality of the file sipp.cpp of the component Command-Line Argument Handler. The manipulation of the argument 3pcc/i/log_file with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
