EUVDB-ID: #VU101062

Risk: Medium

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID: CWE-134 - Use of Externally-Controlled Format String

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a format string error within the HttpRequest object that allows to get the HTTP headers from the server's response after sending the request. The returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. A remote user can create internal strings that can be used to access hidden properties of objects, which can lead to remote code execution.
