CVE-2023-7272 is a high-severity vulnerability affecting Eclipse Parsson versions before 1.0.4 and 1.1.3. This vulnerability allows an attacker to trigger a Java stack overflow exception by providing a document with a deep nesting of objects, which can lead to a denial of service. Given the nature of this vulnerability, organizations using Eclipse Parsson should take immediate action.
The CVSS score for this vulnerability is 8.6, indicating a high severity level. The attack vector is network-based, and the attack complexity is low, meaning that attackers can exploit this vulnerability without requiring special conditions. The urgency for patching is high, as the potential impact on availability can disrupt services.
Risk to organizations includes potential downtime, loss of service availability, and subsequent reputational damage. It is crucial for security teams to prioritize remediation efforts to mitigate the impacts of this vulnerability.
Currently, there are no known exploits or public proof-of-concept available for CVE-2023-7272, yet the nature of the vulnerability necessitates immediate attention from organizations using the affected versions of Eclipse Parsson.
Organizations should prioritize patching immediately. They need to ensure that their systems are updated to the latest versions to prevent potential exploitation.
Vulnerability Details
The official description of CVE-2023-7272 states that it allows an attacker to cause a Java stack overflow exception and denial of service. The vulnerability is categorized under CWE-787, which pertains to improper control of the depth of recursion. The vulnerability affects all versions of Eclipse Parsson prior to 1.0.4 and 1.1.3, and it was published on July 17, 2024.
Technical Analysis
The root cause of this vulnerability lies in the way Eclipse Parsson processes JSON documents. When handling deeply nested objects, the application does not adequately manage stack depth, leading to a stack overflow. The attack vector is network-based, allowing remote attackers to send specially crafted JSON documents. The attack complexity is low, requiring no special privileges or user interaction, making it relatively easy for attackers to exploit. The confidentiality, integrity, and availability impacts are classified as none, none, and high, respectively.
Risk & Impact Analysis
Organizations utilizing Eclipse Parsson must take this vulnerability seriously. The potential for denial of service can significantly affect operations, especially in environments where JSON processing is critical. The availability impact is high, which could lead to service interruptions and financial losses for businesses reliant on the affected software.
The urgent nature of this vulnerability, paired with the ease of exploitation, means organizations must prioritize remediation in their patching cycles. The CVSS score reinforces the need for immediate action, as any delay could result in significant operational disruption.

Affected Versions
Eclipse Parsson versions prior to 1.0.4 and those starting from 1.1.0 up to, but not including, 1.1.3 are affected by this vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to Eclipse Parsson version 1.0.4 or later, or version 1.1.3 or later. If immediate upgrading is not possible, alternative mitigation strategies such as input validation and limiting the depth of nested objects in JSON documents should be implemented.
In addition, organizations can benefit from thorough security assessments, such as application security assessment to identify any other potential weaknesses.
Detection Guidance
Organizations should monitor logs for unusual behavior related to JSON processing and watch for stack overflow exceptions in application logs. Additionally, implementing network-based monitoring can help identify potentially malicious traffic patterns that may target the vulnerability.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2023-7272 lies in the potential for similar vulnerabilities to emerge in JSON processing libraries. Security teams should remain vigilant and implement robust input validation mechanisms to prevent stack overflow vulnerabilities.
This vulnerability highlights a trend wherein software libraries may overlook depth validation in data structures. Lessons learned include the importance of conducting regular security audits and vulnerability assessments.
