5) Input validation error

EUVDB-ID: #VU75217

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-26049

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient input validation when parsing cookies. A remote attacker can send a specially crafted HTTP request with a cookie value that starts with a double quote and force the application to read the cookie string until it sees a closing quote. Such behavior can be used to exfiltrate sensitive values from other cookies.

Mitigation

Install updates from vendor's website.
