CVE-2023-2665Network attack vector

Salary-data disclosure via predictable attachment filenames

Published May 12, 2023 · Updated Jan 24, 2025

Information disclosure in François Jacquet RosarioSIS before 11.0 allows remote attackers to read sensitive salary attachments. The salaries module stores uploads under predictable, timestamp-derived filenames while their web paths lack access control. No account or user interaction is required; filename enumeration exposes salary data but does not alter records or interrupt service.
