Santesoft Sante PACS Server Stack-based Buffer Overflow

During login to the web server in "Sante PACS Server.exe", OpenSSL function EVP_DecryptUpdate is called to decrypt the username and password. A fixed 0x80-byte stack-based buffer is passed to the function as the output buffer. A stack-based buffer overflow exists if a long encrypted username or password is supplied by an unauthenticated remote attacker.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days
