Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the Cookie.parse function, which uses an insecure regular expression. This vulnerability has a CVSS score of 5.3, indicating a medium severity level. The implications of this vulnerability can lead to service disruptions, which is a significant concern for organizations utilizing this package.
The risk to organizations includes potential downtime or degraded performance due to excessive resource consumption when exploiting the vulnerability. As such, it is crucial for organizations to address this vulnerability in their systems promptly.
Currently, there are no known exploits or public proof of concepts (PoCs) available for this vulnerability. However, the nature of the vulnerability suggests that it could be leveraged in a targeted attack scenario. Therefore, organizations should prioritize patching immediately.
Given the potential impacts, organizations should assess their usage of the cookiejar package and implement the necessary patches to ensure the security of their applications.
Vulnerability Details
The cookiejar vulnerability is classified under CWE-1333, which pertains to Regular Expression Denial of Service. The affected versions include all versions prior to 2.1.4.
The vulnerability was published on January 18, 2023, and has been classified as medium severity based on a CVSS score of 5.3. The attack vector is network-based, with low complexity and no privileges required for exploitation.
Technical Analysis
The root cause of the vulnerability lies in the insecure regular expression utilized within the Cookie.parse function of the cookiejar package. This flawed implementation allows attackers to craft malicious input that could lead to excessive resource consumption, thereby causing denial of service.
The attack vector is network-based, and the complexity is low, meaning that an attacker could exploit this vulnerability without requiring advanced technical skills. Since no user interaction is needed, the attack can be executed remotely, increasing the risk.
The vulnerability affects availability, as it can lead to service disruptions. However, it does not impact confidentiality or integrity.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability can lead to significant service downtimes, impacting user experience and trust. Organizations leveraging the cookiejar package need to recognize the blast radius potential, especially if the vulnerable software is part of a larger application ecosystem.
The urgency for organizations to address this vulnerability is classified as high. Given the medium CVSS score and the potential for denial of service, organizations should take immediate action to patch their systems.
