CVE-2017-15054
HIGHCVE-2017-15054 is a high-severity (CVSS 7.5) vulnerability in nilsteampassnet/teampass. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2017-15054 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
TeamPass arbitrary file upload vulnerability
Blast Radius
nilsteampassnet/teampassReal-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
An arbitrary file upload vulnerability, present in TeamPass before 2.1.27.9, allows remote authenticated users to upload arbitrary files leading to Remote Command Execution. To exploit this vulnerability, an authenticated attacker has to tamper with parameters of a request to upload.files.php, in order to select the correct branch and be able to upload any arbitrary file. From there, it can simply access the file to execute code on the server.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nilsteampassnet/teampass. 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 nilsteampassnet/teampass to 2.1.27.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-15054 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-2017-15054 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-2017-15054. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
