CVE-2024-2323: Password Brute Force via Password History Validation in Multiple WSO2 Products Allows User Account Discovery

Noroxi assessment

Priority: Monitor (action score 19/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The RemoteUserStoreManagerService does not sufficiently validate password change attempts when the password history validation feature is enabled. This oversight allows an attacker to repeatedly attempt password guesses for a user account without being adequately restricted. Exploiting this vulnerability enables an attacker to discover a user's password through brute force, leading to account impersonation. The success rate of such an attack is influenced by the complexity of the targeted user's password, with simpler passwords increasing the likelihood of compromise.
