Technical details
This is a cleartext storage vulnerability affecting the AsyncJob storage mechanism in Apache CloudStack's database layer. Sensitive information that should be encrypted is instead stored in plaintext in AsyncJob records, making it accessible to any database user or attacker with database access. The vulnerability affects versions 4.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0. No special authentication or network access is required beyond database access. The attack vector is primarily local/adjacent (database access), and the impact is information disclosure of sensitive credentials and configuration data. Patches are available in versions 4.20.3.1, 4.22.1.1, and later.
