What is CVE-2018-11772?

CVE-2018-11772 is a high-severity SQL injection vulnerability in Apache VCL, published on 29 Jul 2019. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

Apache VCL versions 2.1 through 2.5 do not properly validate cookie input when determining what node (if any) was previously selected in the privilege tree. The cookie data is then used in an SQL statement. This allows for an SQL injection attack. Access to this portion of a VCL system requires admin level rights. Other layers of security seem to protect against malicious attack. However, all VCL systems running versions earlier than 2.5.1 should be upgraded or patched. This vulnerability was found and reported to the Apache VCL project by ADLab of Venustech.

Weakness: CWE-89
