SCA: security update for github.com/argoproj/argo-cd/v2 (GHSA-2vgg-9h6w-m454)

critical Tenable Cloud Security Plugin ID 409107

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.8.13, 2.9.9,
 and 2.10.4, an attacker can effectively bypass the rate limit and brute force protections by exploiting
 the application's weak cache-based mechanism. This loophole in security can be combined with other
 vulnerabilities to attack the default admin account. This flaw undermines a patch for CVE-2020-8827
 intended to protect against brute-force attacks. The application's brute force protection relies on a
 cache mechanism that tracks login attempts for each user. This cache is limited to a `defaultMaxCacheSize`
 of 1000 entries. An attacker can overflow this cache by bombarding it with login attempts for different
 users, thereby pushing out the admin account's failed attempts and effectively resetting the rate limit
 for that account. This is a severe vulnerability that enables attackers to perform brute force attacks at
 an accelerated rate, especially targeting the default admin account. Users should upgrade to version
 2.8.13, 2.9.9, or 2.10.4 to receive a patch. (CVE-2024-21662)
