How do I detect CVE-2012-1605 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2012-1605 if there is no patch (or I can't update yet)?

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.

Is CVE-2012-1605 actively exploited in the wild?

No public exploit code has been indexed for CVE-2012-1605 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-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

The Extbase Framework in TYPO3 4.6.x through 4.6.6, 4.7, and 6.0 unserializes untrusted data, which allows remote attackers to unserialize arbitrary objects and possibly execute arbitrary code via vectors related to "a missing signature (HMAC) for a request argument."
