CVE-2022-25844: 
JavaScript vulnerability analysis and mitigation

The vulnerability CVE-2022-25844 affects the Angular package versions 1.7.0 and higher, which has been identified as susceptible to Regular Expression Denial of Service (ReDoS). This security flaw was discovered and disclosed on April 21, 2022. The vulnerability allows attackers to exploit the system by providing a custom locale rule that manipulates the parameter in posPre through NUMBER_FORMATS.PATTERNS[1].posPre with extremely high values (Snyk, NVD). It's important to note that this package has been deprecated and is no longer maintained.

The vulnerability is classified with a CVSS v3.1 base score of 7.5 (HIGH), indicating its significant severity. The attack vector is network-based, with low attack complexity and requires no privileges or user interaction. The vulnerability specifically targets the number formatting functionality in Angular's locale system, where an attacker can manipulate the posPre parameter using the .repeat() method with extremely high values to trigger the ReDoS condition (Snyk, NetApp).

When successfully exploited, this vulnerability can lead to a Denial of Service condition by causing the system to process extremely large regular expressions, resulting in excessive CPU consumption. The impact primarily affects the availability of the system, while maintaining the confidentiality and integrity of the affected component (Snyk).

There is no fixed version available for this vulnerability as the Angular package has been deprecated and is no longer maintained. Organizations using affected versions should consider migrating to alternative, supported frameworks (Snyk, CVE).
