CVE-2023-0833 is a medium-severity vulnerability found in Red Hat's AMQ-Streams, which utilizes the OKHttp component. This flaw allows for information disclosure via an exception triggered by an illegal value in a header. The vulnerability could enable an authenticated attacker to access information beyond their normal permissions.
The CVSS score for this vulnerability is 4.7, indicating a medium severity level. This means that organizations utilizing affected versions of the AMQ-Streams should give this matter immediate attention to mitigate potential risks.
Risk to organizations includes potential unauthorized access to sensitive information, which could lead to data breaches or compliance violations. Therefore, organizations should prioritize patching immediately.
Currently, there are no known exploits publicly available for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. However, the potential for exploitation remains a concern, highlighting the importance of timely remediation.
Vulnerability Details
The vulnerability described in CVE-2023-0833 arises from a flaw in the OKHttp component utilized by Red Hat's AMQ-Streams. Officially, it is classified under CWE-209, indicating an information exposure issue.
The vulnerability was published on September 27, 2023, and affects versions of the AMQ-Streams that ship with the vulnerable OKHttp version prior to 4.9.2. The specific impact is classified as high for confidentiality, with no integrity or availability impact.
The CVSS vector string for this vulnerability is CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N, indicating a local attack vector, high complexity, low privileges required, and no user interaction necessary.
Technical Analysis
The root cause of CVE-2023-0833 is an improper handling of exceptions triggered by illegal header values in the OKHttp component. This leads to the exposure of sensitive information that should remain inaccessible to unauthorized users.
The attack vector is classified as local, meaning that an attacker must have access to the local network where the vulnerable application is running. The attack complexity is high, requiring specific conditions to be met, but the privileges required are low, allowing authenticated users to exploit this flaw without additional escalations.
User interaction is not required for the vulnerability to be exploited, which further raises the risk for organizations. The confidentiality impact is high, as sensitive data can be disclosed, while integrity and availability impacts are assessed as none.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-0833 is significant, particularly for organizations that rely on the AMQ-Streams for messaging and communication. The potential for unauthorized access to sensitive information poses a serious threat, potentially leading to data breaches and compliance issues.
Organizations should address this vulnerability in their priority patch cycle, especially those operating in regulated environments or handling sensitive data. The blast radius could be extensive if the vulnerability is exploited, as it may lead to the exposure of multiple user accounts and sensitive information.
Given the CVSS score of 4.7 and the absence of known exploits, organizations should still treat this vulnerability with urgency, as the potential for risk is non-negligible.
