CVE-2021-43257

Name of the Vulnerable Software and Affected Versions MantisBT versions prior to 2.25.3

Description The issue is related to the lack of neutralization of formula elements in the CSV API, allowing an unprivileged attacker to execute code or gain access to information when a user opens a generated CSV file in Excel. This occurs when the csv export.php file is opened in Excel.

Recommendations For versions prior to 2.25.3, update to version 2.25.3 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the CSV API or restricting access to the csv export.php file until the update is applied.
