Given the potential for significant impact, organizations utilizing affected versions of Apache should act swiftly to mitigate the risks associated with this vulnerability.
Vulnerability Details
A partial fix for CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 ignores some uses of the legacy content-type based configuration of handlers. The "AddType" and similar configurations, when files are requested indirectly, can result in the disclosure of local content, including PHP scripts that may be served instead of interpreted.
This vulnerability falls under the CWE-668 category, which relates to the exposure of sensitive information through a configuration oversight. The vulnerability was published on July 18, 2024, and is classified as medium severity with a CVSS score of 5.3.
Technical Analysis
The root cause of this vulnerability lies in the handling of legacy content-type based configurations, where certain indirect file requests can lead to unintended source code disclosure. The attack vector is network-based, with low complexity, requiring no privileges or user interaction. This vulnerability has a confidentiality impact classified as low, with no integrity or availability impact.
Risk & Impact Analysis
In a real-world deployment, this vulnerability poses a risk of source code disclosure, which can be exploited by attackers to gain insights into application logic or to execute further attacks against the server. The potential blast radius includes any organization relying on affected versions of Apache HTTP Server, emphasizing the significance of immediate action.
With a CVSS score of 5.3, the urgency assessment indicates that organizations should address this vulnerability in their priority patch cycle. The knowledge of a known exploit further intensifies the need for swift remediation.
