CVE-2023-46402 is a high-severity vulnerability found in git-urls version 1.0.0. This vulnerability allows for a Regular Expression Denial of Service (ReDOS) in the urls.go file, which could lead to significant service disruption. Given its CVSS score of 7.5, organizations using this version should treat it with urgency.
Risk to organizations includes potential downtime and degraded service performance due to the ReDOS attack vector. Attackers may leverage this vulnerability to exploit the application, causing applications to become unresponsive. It is crucial for organizations to assess their exposure to this vulnerability.
Currently, there is no known exploit publicly available, but the nature of the vulnerability and its high impact score signify that it should be prioritized in the patching cycle. Organizations should prioritize patching immediately.
The vulnerability was published on November 18, 2023, and organizations using affected versions must ensure that they address this issue promptly to mitigate risks.
Vulnerability Details
The vulnerability is classified under CWE-1333, indicating it involves issues related to improper handling of regular expressions. The CVSS vector string is "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", which outlines that the attack vector is network-based, with low complexity and no privileges required for exploitation.
The affected product is git-urls, specifically version 1.0.1. Organizations should consider upgrading to a patched version as soon as it becomes available.
Technical Analysis
The root cause of this vulnerability lies in the handling of regular expressions within the urls.go file of the git-urls package. The attack vector is network-based, meaning that an attacker can exploit the system remotely without any local access. The complexity of the attack is low, requiring no special privileges or user interaction to initiate.
The exploitation of this vulnerability can lead to high availability impact, as services can become temporarily unavailable, affecting user access and potentially leading to data loss.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-46402 is significant, particularly for organizations relying on git-urls for critical operations. The potential for service disruption is high, which can lead to loss of user trust and increased operational costs.
Organizations should assess their current environment and implement necessary changes to reduce the blast radius of this vulnerability. Given the CVSS score of 7.5, it is imperative to address this vulnerability in the next patch cycle.
