CVE-2021-25294 (GCVE-0-2021-25294)

Vulnerability from cvelistv5 – Published: 2021-01-18 05:28 – Updated: 2024-08-03 19:56

Summary

OpenCATS through 0.9.5-3 unsafely deserializes index.php?m=activity requests, leading to remote code execution. This occurs because lib/DataGrid.php calls unserialize for the parametersactivity:ActivityDataGrid parameter. The PHP object injection exploit chain can leverage an __destruct magic method in guzzlehttp.

Severity

No CVSS data available.
