LLM-synthesized narrative grounded in this CVE's description and references.
Tenda G0 v15.11.0.5 has a stack overflow in picCropName, allowing DoS or RCE via crafted HTTP requests.
Vulnerability
A stack overflow vulnerability exists in the picCropName parameter within the formCropAndSetWewifiPic function in Shenzhen Tenda Technology Co., Ltd Tenda G0 v15.11.0.5 [1]. The vulnerable code path is reachable when any parameter from websGetVar is not null, as the picCropName value is used in a subsequent snprintf command and doSystemCmd execution [1].
Exploitation
An attacker can exploit this vulnerability by sending a crafted HTTP request to the formCropAndSetWewifiPic CGI endpoint. The request must include a sufficiently long value for the picCropName parameter, such as a string of 888 or more characters, to trigger the stack overflow [1].
Impact
Successful exploitation of this vulnerability can lead to a Denial of Service (DoS) due to a process crash or device instability. Additionally, it may allow for Arbitrary Code Execution (ACE) [1].
Mitigation
No patched version or specific mitigation details are disclosed in the available references. The affected version is Tenda G0 v15.11.0.5 [1].
