CWE-79

Description

An improper neutralization of input vulnerability was identified in GitHub Enterprise Server that allowed user-supplied HTML to inject DOM elements with IDs that collided with server-initialized data islands. These collisions could overwrite or shadow critical application state objects used by certain Project views, leading to unintended server-side POST requests or other unauthorized backend interactions. Successful exploitation requires an attacker to have access to the target GitHub Enterprise Server instance and to entice a privileged user to view crafted malicious content that includes conflicting HTML elements. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.18.3, 3.17.9, 3.16.12, 3.15.16, and 3.14.21.

Affected configurations

• github enterprise server (< 3.14.21) • github enterprise server (>= 3.15.0 < 3.15.16) • github enterprise server (>= 3.16.0 < 3.16.12) • github enterprise server (>= 3.17.0 < 3.17.9) • github enterprise server (>= 3.18.0 < 3.18.3)
