Requires prior database access (PR:H); weak MD5 makes cracking trivial (AC:L); impact is plaintext credential recovery (C:H) with no integrity or availability effect.

admin3 through 3.0.0 stores account passwords using single-round MD5 with only the username as salt and no key derivation function. Attackers with database access can recover plaintext passwords through offline dictionary or brute-force attacks due to negligible computational effort.
AnalysisAI
Password cracking in admin3 3.0.0 and earlier allows anyone who obtains the application's credential database to recover user plaintext passwords offline, because stored credentials use single-round MD5 salted only with the username and no key-derivation function. The flaw does not grant database access by itself - it requires a prior compromise (database breach, SQL injection, exposed backup, or insider/privileged access, reflected by the CVSS PR:H prerequisite), but once that precondition is met, cracking is trivial on commodity hardware; publicly available exploit code exists. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to first possess the admin3 credential database (the stored username + MD5 password records) - obtained via a separate database breach, SQL injection, backup exposure, or privileged/insider access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but conditional (low-to-moderate) risk, correctly reflected by the vendor's 4.9 medium score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch was identified at time of analysis, so remediation is a migration rather than a version bump: replace SecurityUtil's single-round MD5 scheme with bcrypt, scrypt, Argon2id, or PBKDF2-HMAC-SHA-256 using a unique cryptographically random per-user salt and a calibrated work factor, and support a re-hash-on-next-successful-login path so existing hashes are gradually upgraded. … Detailed patch versions, workarounds, and compensating controls in full report. |
