CVE-2022-40149 affects the Jettison library, allowing users to parse untrusted XML or JSON data. This vulnerability allows attackers to conduct Denial of Service (DoS) attacks by causing the parser to crash through stack overflow when processing user-supplied input. The severity of this issue is classified as medium (CVSS score of 6.5), though it can result in high availability impact.
The risk to organizations includes potential downtime and service interruptions. As the parser is used in various applications, a successful attack could disrupt critical web services or applications relying on this library. It is crucial for organizations utilizing Jettison to prioritize patching this vulnerability immediately.
Currently, there are no known public exploits or proof of concept (PoC) available for this vulnerability, which suggests that while it is a significant concern, active exploitation is not widespread. However, the nature of vulnerabilities in parsing libraries necessitates immediate attention to prevent possible exploitation.
Organizations should ensure they are using versions of Jettison that are not affected by this vulnerability. It is advisable to monitor for any updates or patches released by the maintainers of Jettison.
Vulnerability Details
Those using Jettison to parse untrusted XML or JSON data may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack.
The primary affected products include versions of Jettison up to 1.4.0 and Debian Linux versions 10.0 and 11.0. The vulnerability has a CWE classification of CWE-121 and CWE-787, indicating issues related to stack overflow and improper restriction of operations within the bounds of a memory buffer.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input in the Jettison parser. Attackers may exploit this flaw by providing crafted XML or JSON data that triggers a stack overflow, leading to a crash of the application utilizing the parser.
The attack vector is categorized as network-based, with low complexity due to the straightforward nature of how the input can be crafted. The attack requires low privileges and does not necessitate user interaction, making it accessible for potential attackers.
The impact assessment indicates a high availability impact, as a successful exploitation could bring down services relying on the Jettison library. There are no confidentiality or integrity impacts associated with this vulnerability.
Risk & Impact Analysis
The real-world risk posed by this vulnerability includes service disruptions for organizations using Jettison in their applications. The blast radius can be considerable, especially for web services that are heavily reliant on XML or JSON parsing.
Given the CVSS score of 6.5, organizations should address this issue in their priority patch cycle. The lack of public exploits is a relief, but as seen with similar vulnerabilities, it is crucial to act swiftly to mitigate any potential threats.
