Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU82980

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-27043

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass filtration.

The vulnerability exists due to insufficient validation of user-supplied input when parsing email address with a special character. A remote attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain.

Mitigation

Update the affected package python3.10 to the latest version.
