Low 3.1
In plain English
A low-severity path traversal in FreeRDP from FreeRDP. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
FreeRDP before 3.32.0 contains a path traversal vulnerability in convert_filedescriptors_to_file_list() in winpr/libwinpr/clipboard/synthetic_file.c, which concatenates server-supplied cFileName values from FileGroupDescriptorW clipboard data into the published local file:// URI without rejecting '/' or '..' sequences. A malicious RDP server can supply '../' sequences so the user's next clipboard paste copies an arbitrary local file readable by the client user instead of the expected remote file.
