CVE-2024-9506 is classified as a low-severity vulnerability due to a CVSS score of 3.7. This vulnerability allows for a potential regular expression denial of service, stemming from an improper regular expression in Vue's parseHTML function. While it may not be immediately critical, the risk to organizations includes potential service disruptions if the vulnerability is exploited.
The vulnerability was published on October 15, 2024, and while it is not currently high-profile, organizations using Vue should be aware of its implications. The attack vector for this vulnerability is network-based, and it requires no privileges or user interaction, making it relatively approachable for attackers.
Given the nature of this vulnerability and its potential impact, organizations should prioritize patching immediately to mitigate the risk of denial of service attacks. The urgency is underscored by the fact that a public proof of concept has been found on GitHub, which could facilitate exploitation.
Organizations should conduct a thorough assessment of their usage of Vue and implement necessary remediation measures to prevent any possible exploitation stemming from this vulnerability.
Vulnerability Details
The official description for CVE-2024-9506 states that it involves an improper regular expression in Vue's parseHTML function that leads to a potential regular expression denial of service vulnerability. The vulnerability is classified under CWE-1333.
The CVSS version 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L, indicating that while the availability impact is low, the attack complexity is high, requiring a detailed understanding to exploit.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of regular expressions within the parseHTML function. Attackers may leverage this to create inputs that cause the function to consume excessive resources, potentially leading to a denial of service.
The attack vector is network-based, meaning that an attacker can initiate an attack remotely. The attack complexity is rated as high, suggesting that while exploitation is possible, it may require specific conditions to succeed. No privileges are required, and user interaction is not needed for the attack to take place.
The impacts on confidentiality and integrity are nonexistent, while the availability impact is low, meaning that the successful exploitation could lead to service interruptions but not data breaches or unauthorized access.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-9506 lies in the potential for denial of service, which could disrupt services relying on Vue's parseHTML function. Given that this vulnerability has a CVSS score of 3.7 and is classified as low severity, organizations should address it in their priority patch cycle.
This vulnerability represents a risk to any organization utilizing Vue, particularly those with high traffic or critical applications where service disruptions could lead to significant downtime or loss of revenue.
Given the implications of this vulnerability and the availability of a public proof of concept, organizations should take proactive measures to mitigate risks associated with this vulnerability.
