Name of the Vulnerable Software and Affected Versions H3C Magic B0 versions prior to 100R002

Description A remote stack-based buffer overflow occurs due to improper handling of the param argument within the SetMobileAPInfoById() function located in the /goform/aspForm file. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the /goform/aspForm file or avoid using the SetMobileAPInfoById() function.
