What is CVE-2015-4410?

CVE-2015-4410 is a high-severity improper input validation vulnerability in moped (rubygems), affecting versions < 1.5.3. It is fixed in 1.5.3, 2.0.5. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.

How severe is CVE-2015-4410?

CVE-2015-4410 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 moped are affected by CVE-2015-4410?

moped (rubygems) versions < 1.5.3 is affected.

Is there a fix for CVE-2015-4410?

Yes. CVE-2015-4410 is fixed in 1.5.3, 2.0.5. Upgrade to this version or later.

Is CVE-2015-4410 exploitable, and should I be worried?

Whether CVE-2015-4410 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-2015-4410 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-2015-4410?

Upgrade: moped to 1.5.3 or later, moped to 2.0.5 or later.

Summary

Moped Rubygem Data Injection Vulnerability

The Moped::BSON::ObjecId.legal? method in rubygem-moped before commit dd5a7c14b5d2e466f7875d079af71ad19774609b allows remote attackers to cause a denial of service (worker resource consumption) or perform a cross-site scripting (XSS) attack via a crafted string.

Impact

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

CVE-2015-4410 has a CVSS score of 7.5 (High). The vector is network-reachable, no 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 (1.5.3, 2.0.5); upgrading removes the vulnerable code path.

Affected versions

moped (< 1.5.3) moped (>= 2.0.0, < 2.0.5)

Security releases

moped → 1.5.3 (rubygems) moped → 2.0.5 (rubygems)

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.
