A vulnerability identified as CVE-2022-28330 affects Apache HTTP Server versions 2.4.53 and earlier. This vulnerability allows attackers to read beyond bounds when the server is configured to process requests using the mod_isapi module. The vulnerability has been classified with a CVSS score of 5.3, indicating a medium severity level.
Risk to organizations includes potential exposure of sensitive data through improper request handling. As this vulnerability can be exploited remotely and requires no user interaction, it poses a significant risk to systems relying on vulnerable Apache HTTP Server configurations.
Organizations should prioritize patching immediately. The vulnerability was published on June 9, 2022, and has since been modified, indicating ongoing updates and potential changes in its risk profile.
As of the latest intelligence, there are no confirmed public exploits or proofs of concept. However, given the nature of the vulnerability, proactive measures should be taken to secure affected systems.
Vulnerability Details
The official description of this vulnerability states: 'Apache HTTP Server 2.4.53 and earlier on Windows may read beyond bounds when configured to process requests with the mod_isapi module.' This vulnerability falls under the CWE-125 classification, which relates to out-of-bounds read issues.
The CVSS score for this vulnerability is 5.3, indicating medium severity. The attack vector is network-based, with low complexity, and requires no privileges or user interaction for exploitation. The confidentiality impact is low, meaning that some sensitive data could be exposed, while integrity and availability impacts are none.
The vulnerability affects Apache's HTTP Server component. All versions prior to the vendor patch are susceptible to this issue.
Technical Analysis
The root cause of this vulnerability lies in the processing logic of the mod_isapi module within the Apache HTTP Server. Specifically, it fails to properly validate input, allowing for out-of-bounds memory access. The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely.
The attack complexity is low, indicating that exploiting this vulnerability does not require sophisticated techniques. Importantly, no privileges are required, and no user interaction is needed to trigger the vulnerability. The confidentiality impact is low, as attackers may access sensitive data, but the integrity and availability impacts are not affected.
Risk & Impact Analysis
Organizations using affected versions of Apache HTTP Server face risks associated with potential data exposure and unauthorized access. The blast radius could extend to any system utilizing the vulnerable configuration, highlighting the need for immediate action.
Given the medium severity and the lack of exploit confirmation, organizations should schedule remediation as part of their regular patch management cycle. However, they should remain vigilant, as the vulnerability's characteristics suggest that it could be targeted by remote attackers.
