CVE-2022-26306 (GCVE-0-2022-26306)

Vulnerability from cvelistv5 – Published: 2022-07-25 00:00 – Updated: 2024-08-03 05:03

Title

Execution of Untrusted Macros Due to Improper Certificate Validation

Summary

LibreOffice supports the storage of passwords for web connections in the user’s configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the required initialization vector for encryption was always the same which weakens the security of the encryption making them vulnerable if an attacker has access to the user's configuration data. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.1.

Severity

No CVSS data available.
