Stack-based Buffer Overflow

A vulnerability was found in Tenda FH451 1.0.0.9. This impacts the function fromSetCfm of the file /goform/setcfm. The manipulation of the argument funcname/funcpara1 results in stack-based buffer overflow. The attack may be performed from remote. The exploit has been made public and could be used.Show less

PJSIP is a free and open source multimedia communication library written in C. Prior to version 2.17, there is a stack buffer overflow vulnerability when pjmedia-codec parses an RTP payload contain more frames than the caller-provided frames can hold. This issue has been patched in version 2.17.Show less

A vulnerability was identified in Wavlink WL-NU516U1 V240425. This vulnerability affects the function sub_401A0C of the file /cgi-bin/login.cgi. Such manipulation of the argument ipaddr leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure.Show less

A stack buffer overflow vulnerability exists in the Wincor Nixdorf wnBios64.sys kernel driver (version 1.2.0.0) in the IOCTL handler for code 0x80102058. The vulnerability is caused by missing bounds checking on the user-controlled Options parameter before copying data into a 40-byte stack buffer (Src[40]) using memmove. An attacker with local access can exploit this vulnerability by sending a crafted IOCTL request with Options > 40, causing a stack buffer overflow that may lead to kernel code execution, local privilege escalation, or denial of service (system crash). Additionally, the same IOCTL handler can leak kernel addresses and other sensitive stack data when reading beyond the buffer boundaries.Show less
