CVE-2023-30253
HIGHCVE-2023-30253 is a high-severity (CVSS 8.8) OS Command Injection vulnerability in dolibarr/dolibarr. 7 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2023-30253 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Dolibarr vulnerable to remote code execution via uppercase manipulation
Real-World Exposure
dolibarr/dolibarrReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Dolibarr before 17.0.1 allows remote code execution by an authenticated user via an uppercase manipulation: <?PHP instead of <?php in injected data.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dolibarr/dolibarr. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update dolibarr/dolibarr to 17.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30253 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-30253 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-30253. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-30253 in your dependencies?
O3 detects CVE-2023-30253 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
