Sante PACS Server: Use of Password Hash With Insufficient Computational Effort
CVE-2025-2265 is a high-severity use of password hash with insufficient computational effort vulnerability in Sante PACS Server from Santesoft, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Sante PACS Server versions: 4.1.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
The password of a web user in "Sante PACS Server.exe" is zero-padded to 0x2000 bytes, SHA1-hashed, base64-encoded, and stored in the USER table in the SQLite database HTTP.db. However, the number of hash bytes encoded and stored is truncated if the hash contains a zero byte

The underlying weakness: Use of Password Hash With Insufficient Computational Effort
The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive.
How developers prevent this class of flaw
- When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
