The package react-native-reanimated before 3.0.0-rc.1 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper usage of regular expression in the parser of Colors.js. This vulnerability allows attackers to exploit the application's regular expression handling, potentially leading to service disruptions.
The severity level of this vulnerability is medium, with a CVSS score of 5.3. This indicates a moderate risk, particularly for applications that rely heavily on the affected package for their operations. Organizations should be particularly alert to this issue, as it may lead to performance degradation or denial of service.
As of the latest update, there is no known exploit available in the wild for this vulnerability. However, it remains crucial for organizations utilizing this package to stay informed and apply patches promptly to avoid potential exploitation.
Organizations should prioritize patching immediately. Failure to address this vulnerability may lead to significant operational risks.
Vulnerability Details
The vulnerability is classified under CWE-1333, indicating an issue with improper regular expression usage. The affected product is the SWMansion react-native-reanimated package, specifically versions prior to 3.0.0-rc.1. The vulnerability was published on September 30, 2022, and has since been modified.
Technical Analysis
The root cause of this vulnerability lies in the improper implementation of regular expressions within the Colors.js parser. This can result in a ReDoS attack where attackers use crafted input to exploit the regular expression's performance characteristics, leading to excessive resource consumption.
The attack vector is network-based, requiring no authentication or user interaction, which increases the vulnerability's potential impact. The attack complexity is low, meaning that the vulnerability can be exploited easily with minimal technical skill.
Regarding impact, the vulnerability has a low availability impact and does not affect confidentiality or integrity, which indicates that while it can disrupt services, it does not compromise data security.
Risk & Impact Analysis
Real-world deployment risks from this vulnerability include potential service outages, particularly for applications utilizing react-native-reanimated in their core functionality. This can lead to loss of user trust and revenue if not mitigated effectively.
Organizations should assess the impact this vulnerability may have on their operations and prioritize remediation in their patching cycles, especially if they depend on this package for critical functionalities.
The urgency for remediation is classified as medium, suggesting that while immediate action may not be critical, organizations should include this vulnerability in their upcoming patch cycles.

Affected Versions
The vulnerable versions of the react-native-reanimated package are all versions prior to 3.0.0-rc.1. Organizations should review their implementations and ensure that they are not using any affected versions.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to react-native-reanimated version 3.0.0-rc.1 or later. If immediate upgrading is not possible, consider implementing workarounds such as input validation or limiting the scope of user input to mitigate the risk of ReDoS attacks.
For further guidance on securing applications, organizations may consider engaging in penetration testing to identify similar weaknesses.
Detection Guidance
Monitoring logs for irregularities in application behavior can be vital for early detection of exploitation attempts. Look for anomalies in user input handling and resource consumption patterns that may indicate a ReDoS attack.
Implementing network-level controls to limit the rate of user input processing can also aid in detection and prevention of potential attacks.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2022-24373 highlights the importance of rigorous testing for regular expression vulnerabilities in code. This incident illustrates a pattern of vulnerabilities that can emerge from improper input handling.
Security teams should take this as a lesson to reinforce their code review processes, particularly for libraries that handle dynamic user input. Ensuring that input validation and sanitization mechanisms are robust can mitigate similar risks.
For further insights into application security, organizations may refer to penetration testing methodologies and consider adopting a proactive approach to vulnerability management.
Additionally, staying informed about evolving threats and vulnerabilities through resources like vulnerability management programs can strengthen an organization's defensive posture.
