Summary
TeamPass arbitrary file upload vulnerability
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.
Impact
The application accepts file uploads without adequately restricting the file type or content. Typical impact: remote code execution if the uploaded file can be served and executed on the server.
CVE-2017-15054 has a CVSS score of 7.5 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.1.27.9); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2017-15054? CVE-2017-15054 is a high-severity unrestricted upload of dangerous file types vulnerability in nilsteampassnet/teampass (composer), affecting versions < 2.1.27.9. It is fixed in 2.1.27.9. The application accepts file uploads without adequately restricting the file type or content.
- How severe is CVE-2017-15054? CVE-2017-15054 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of nilsteampassnet/teampass are affected by CVE-2017-15054? nilsteampassnet/teampass (composer) versions < 2.1.27.9 is affected.
- Is there a fix for CVE-2017-15054? Yes. CVE-2017-15054 is fixed in 2.1.27.9. Upgrade to this version or later.
- Is CVE-2017-15054 exploitable, and should I be worried? Whether CVE-2017-15054 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2017-15054 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2017-15054? Upgrade
nilsteampassnet/teampassto 2.1.27.9 or later.
