jq is a command-line JSON processor. In versions up to and including 1.7.1, an integer overflow arises when assigning value using an index of 2147483647, the signed integer limit. This causes a denial of service. The vulnerability is classified under CWE-190. The commit de21386681c0df0104a99d9d09db23a9b2a78b1e contains a patch for the issue. This vulnerability is considered medium severity (CVSS 4.3).
Risk to organizations includes potential denial of service, affecting the availability of services relying on jq. Due to the nature of the vulnerability, it could be exploited via a network attack, making it critical for organizations to assess their exposure.
The urgency for defenders is moderate. Organizations should schedule remediation to address this vulnerability in their environment. While no public exploits are currently confirmed, the existence of this vulnerability necessitates attention.
Given its status and potential impact, organizations utilizing affected versions of jq must take immediate action to mitigate risks associated with this vulnerability.
Vulnerability Details
The official CVE description states: 'jq is a command-line JSON processor. In versions up to and including 1.7.1, an integer overflow arises when assigning value using an index of 2147483647, the signed integer limit. This causes a denial of service.' The CVSS score is 4.3, indicating a medium severity level due to impacts on availability, with a low attack complexity and no privileges required.
Technical Analysis
The root cause of this vulnerability is an integer overflow that occurs when assigning a value using a specific index at the limit of signed integers. The attack vector is network-based, meaning it can be triggered remotely. The attack complexity is low, and no privileges are required for exploitation. User interaction is required, which limits the scope of the attack. The impact on confidentiality and integrity is none, while the availability impact is low, leading to potential service disruptions.
Risk & Impact Analysis
The real-world deployment risk is moderate. Organizations using jq in production environments should be aware of the potential for denial of service due to this vulnerability. This matters because affected systems may experience downtime, affecting operations and service delivery. The blast radius potential is limited to systems directly utilizing jq, but the impact on business continuity could be significant. Organizations should assess their current patch levels and prioritize remediation based on the CVSS score of 4.3.
