CVE-2023-1436 is a medium-severity vulnerability affecting the Jettison library. This vulnerability allows an infinite recursion to be triggered when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. Consequently, this leads to a StackOverflowError exception being thrown, which can potentially disrupt applications utilizing this library.
The CVSS score for this vulnerability is 5.9, indicating a medium level of severity. The attack vector is classified as network-based, and it requires low attack complexity, with no privileges or user interaction needed to exploit it. The availability impact is considered high, meaning that a successful attack could render the affected service unavailable.
Organizations utilizing Jettison should be aware of the potential risks associated with this vulnerability. The infinite recursion can lead to service disruptions, impacting the availability of applications relying on this library. Therefore, timely remediation is crucial to ensure the continuous operation of services.
Given the nature of this vulnerability and its potential impact, organizations should prioritize patching immediately. It is essential to monitor any updates from the vendor regarding remediation steps.
Vulnerability Details
The vulnerability was published on March 22, 2023, and is classified under CWE-674, representing a potential vulnerability related to recursion without termination. The affected version of Jettison includes all versions prior to 1.5.4.
The official CVE description states: "An infinite recursion is triggered in Jettison when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. This leads to a StackOverflowError exception being thrown."
Technical Analysis
Root cause analysis indicates that the vulnerability arises from mishandling self-referential data structures within the Jettison library. The attack vector is network-based, allowing attackers to exploit this condition remotely.
The attack complexity is classified as low, meaning that even less sophisticated attackers could exploit this vulnerability. There are no privileges required for exploitation, nor is any user interaction necessary, further increasing the risk. The vulnerability impacts availability, as successful exploitation can lead to service downtime.
Risk & Impact Analysis
Risk to organizations includes potential service outages and disruptions. The blast radius of this vulnerability can affect any application relying on the Jettison library, especially those with complex data structures that may inadvertently trigger the recursion.
Due to the nature of the vulnerability, organizations should assess their exposure based on the CVSS score and the potential for exploitation in real-world scenarios. Given that the exploitability is rated medium, there is a risk that it could be leveraged by attackers if not mitigated quickly.
Organizations should address this vulnerability in their priority patch cycle to prevent possible exploitation. The urgency is heightened by the fact that the impact on availability may lead to significant operational disruptions.
