Deeper analysis

Koha ILS versions 23.05 and earlier are affected by CVE-2024-28739, a flaw that allows remote code execution when an attacker supplies a crafted script through the format parameter. The vulnerability carries a CVSS 3.1 score of 7.2 and is classified under CWE-77 and CWE-79.

An authenticated attacker with administrative privileges can exploit the issue over the network with low attack complexity and no user interaction, achieving full control over confidentiality, integrity, and availability of the target system.

A public technical write-up demonstrates an XSS vector that can be chained to achieve one-click remote code execution against Koha ILS instances.

The EPSS score is currently 0.23 with an identical peak value, indicating steady rather than sharply rising exploitation interest since disclosure.
