CVE-2020-8115

MEDIUM EXPLOITED NUCLEI

Revive Adserver <= 5.0.3 - Reflected Cross-Site Scripting via afr.php Query String

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2020-8115 has been observed exploited in the wild (reported by VulnCheck KEV). A Nuclei detection template is also available.

Description

A reflected XSS vulnerability has been discovered in the publicly accessible afr.php delivery script of Revive Adserver <= 5.0.3 by Jacopo Tediosi. There are currently no known exploits: the session identifier cannot be accessed as it is stored in an http-only cookie as of v3.2.2. On older versions, however, under specific circumstances, it could be possible to steal the session identifier and gain access to the admin interface. The query string sent to the www/delivery/afr.php script was printed back without proper escaping in a JavaScript context, allowing an attacker to execute arbitrary JS code on the browser of the victim.
