Description

This security bulletin contains information about 2 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2023-26049)

CWE-ID: CWE-20 - Improper input validation

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


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.


2) Incorrect default permissions (CVE-ID: CVE-2023-2976)

CWE-ID: CWE-276 - Incorrect Default Permissions

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


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect default permissions in com.google.common.io.FileBackedOutputStream. A local user with access to the system can view contents of files and directories or modify them.
