Description

This security bulletin contains information about 2 vulnerabilities.


1) Incorrect Regular Expression (CVE-ID: CVE-2022-25927)

CWE-ID: CWE-185 - Incorrect Regular Expression

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation passed via the trim() function. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


2) Inefficient Algorithmic Complexity (CVE-ID: CVE-2022-25881)

CWE-ID: CWE-407 - Inefficient Algorithmic Complexity

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


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

The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.
