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
commons-fileupload:commons-fileuploadReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
The default configuration of javax.servlet.context.tempdir in Apache Commons FileUpload 1.0 through 1.2.2 uses the /tmp directory for uploaded files, which allows local users to overwrite arbitrary files via an unspecified symlink attack.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for commons-fileupload:commons-fileupload, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update commons-fileupload:commons-fileupload to 1.2.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-0248 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-2013-0248 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2013-0248. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
