Detailsinfo

A vulnerability, which was classified as critical, has been found in OpenSatKit 2.2.1. This issue affects an unknown functionality. The manipulation of the argument DirName with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in OpenSatKit 2.2.1. The DirName field in the telecommand is provided by the ground segment and must be treated as untrusted input. The program copies DirName into the local buffer DirWithSep using strcpy. The size of this buffer is OS_MAX_PATH_LEN. If the length of DirName is greater than or equal to OS_MAX_PATH_LEN, a stack buffer overflow occurs, overwriting adjacent stack memory. The path length check (FileUtil_AppendPathSep) is performed after the strcpy operation, meaning the validation occurs too late and cannot prevent the overflow.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2025-70083 since 01/09/2026. The exploitation is known to be easy. Technical details of the vulnerability are known, but there is no available exploit.
