    CVE-2025-40911 – Apache Net::CIDR::Set IP CIDR Leading Zero Vulnerability

    May 27, 2025

    CVE ID : CVE-2025-40911

    Published : May 27, 2025, 10:15 p.m. | 2 hours, 44 minutes ago

    Description : Net::CIDR::Set versions 0.10 through 0.13 for Perl does not properly handle leading zero characters in IP CIDR address strings, which could allow attackers to bypass access control that is based on IP addresses.

    Leading zeros are used to indicate octal numbers, which can confuse users who are intentionally using octal notation, as well as users who believe they are using decimal notation.

    Net::CIDR::Set used code from Net::CIDR::Lite, which had a similar vulnerability CVE-2021-47154.

    Severity: 0.0 | NA
