phpSysInfo allows remote attackers to determine the existence of arbitrary files via a .. (dot dot) sequence
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
phpsysinfo/phpsysinfoReal-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
Directory traversal vulnerability in index.php in phpSysInfo 2.5.1 allows remote attackers to determine the existence of arbitrary files via a .. (dot dot) sequence and a trailing null (%00) byte in the lng parameter, which will display a different error message if the file exists.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpsysinfo/phpsysinfo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update phpsysinfo/phpsysinfo to 3.2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2006-3360 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2006-3360 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2006-3360. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
