USN-6729-1: Apache HTTP Server vulnerabilities

Summary: Recent research has discovered several vulnerabilities in the Apache HTTP Server, which could allow a remote attacker to manipulate the server through HTTP request split attacks or even cause a denial of service (DoS) by consuming server resources.

Details of the Vulnerabilities:

Security experts Orange Tsai, Keran Mu, and Jianjun Chen have pinpointed flaws in the Apache HTTP Server's input validation process. These vulnerabilities, identified primarily through their CVEs—CVE-2023-38709 and CVE-2024-24795—involve potential HTTP request splitting attacks. This type of attack could compromise server integrity and affect communication reliability across networks, posing significant risks to both service providers and users.

Furthermore, Bartek Nowotarski discovered a critical flaw in the HTTP Server HTTP/2 module, represented by CVE-2024-27316. This vulnerability allows an attacker to send endless continuation frames, which could exhaust the server's resources and lead to a denial of service (DoS). This form of attack impacts server availability and can impose a serious threat to continuous internet services and business operations.

Consequences: If these vulnerabilities are exploited, the potential consequences include compromised server security, interrupted service delivery, and in severe cases, total server downtime. Enterprises depending on Apache HTTP Server for their web services need to be particularly cautious and take immediate action to mitigate these risks.

Solution: It is critical for system administrators to update their servers promptly to the latest Apache HTTP Server version which contains the necessary patches for these vulnerabilities. Regular updates and vigilant monitoring of server activities are cornerstone practices that help in maintaining security infrastructure.
