Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU56829

Risk: Medium

CVSSv4.0: 1.7 [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:Green]

CVE-ID: CVE-2021-29923

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to insufficient validation of user-supplied input in net.ParseIP and net.ParseCIDR, as the Go interpreter does not properly consider extraneous zero characters at the beginning of an IP address octet. A remote attacker can bypass access control that is based on IP addresses, because of unexpected octal interpretation.

Mitigation

Install updates from vendor's repository.
