TECH STACK: Apache HTTP Server

DATE(S) ISSUED: 02/10/2023

NVD LAST MODIFIED: 11/02/2023

CRITICALITY: CRITICAL

OVERVIEW: This advisory alerts to the critical risk associated with running unsupported versions of Apache HTTP Server, specifically versions 2.1.x through 2.2.x. These versions have reached End of Life (EOL) and are no longer receiving security updates or patches from the vendor. Running unsupported software increases the vulnerability of your systems to security breaches and attacks due to unpatched vulnerabilities.

VULNERABILITY DETAILS:

• Unsupported Version Range: Apache HTTP Server versions between 2.1.x and 2.2.x.
• Risk: The lack of vendor support means these versions will not receive updates for new vulnerabilities, leaving systems at risk for exploitation.

SOLUTION/MITIGATION:

• Required Action: Upgrade to a currently supported version of Apache HTTP Server immediately. It is crucial to transition to a version that receives regular security updates to mitigate potential vulnerabilities.
• Resources: Review the official Apache announcement and upgrade guidance here: Apache 2.2 End of Life Announcement.

ADDITIONAL INFORMATION:

• Severity: The risk associated with running EOL software is deemed critical, with a potential impact rating of high regarding confidentiality, integrity, and availability.
• CVSS Scores: Both CVSS v2 and v3 scores are at the highest severity rating of 10, indicating the utmost level of risk due to the unavailability of patches for newly discovered vulnerabilities.

VERIFICATION:

• Conduct a scan to identify any instances of Apache HTTP Server within the version range of 2.1.x to 2.2.x.
• Verify the version post-upgrade to ensure compliance with supported versions.

ACTION ITEMS:

1. Audit: Immediately identify any installations of Apache HTTP Server versions 2.1.x to 2.2.x.
2. Plan: Develop a migration plan to upgrade affected systems to a supported version of Apache HTTP Server.
3. Execute: Promptly implement the upgrade plan to mitigate exposure to unpatched vulnerabilities.
4. Monitor: Continuously monitor for any advisories related to the Apache HTTP Server to ensure systems remain within supported versions.

Failure to upgrade from these unsupported versions exposes your infrastructure to significant security risks. Immediate action to upgrade to supported versions will help safeguard your systems against potential vulnerabilities and ensure the continued security of your network environment.
