CVE-2018-25357: Dolibarr ERP CRM contains a remote code evaluation vulnerability

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
• EPSS 1.7%, percentile 77: FIRST’s model estimates a 1.7% chance of exploitation activity in the next 30 days, higher than 77% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes dolibarr/dolibarr (Composer (PHP)) >= 7.0.0, <= 7.0.3, fixed in 7.0.4; dolibarr/dolibarr (Composer (PHP)) < 6.0.8, fixed in 6.0.8. Check your lockfile, including transitive dependencies.

What it is

Dolibarr ERP CRM 7.0.3 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting PHP code through the dbname parameter. Attackers can send a POST request to install/step1.php with malicious PHP code in the dbname parameter, then execute commands via the check.php endpoint using the cmd GET parameter.
