CVE-2014-0114 is a high-severity code injection vulnerability in Apache Struts, published on 30 Apr 2014. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description Apache Commons BeanUtils, as distributed in lib/commons-beanutils-1.8.0.jar in Apache Struts 1.x through 1.3.10 and in other products requiring commons-beanutils through 1.9.2, does not suppress the class property, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via the class parameter, as demonstrated by the passing of this parameter to the getClass method of the ActionForm object in Struts 1.

What it is: CVE-2014-0114 is a high-severity code injection vulnerability in Apache Struts, published on 30 Apr 2014. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2014-0114 exists. Affected packages and fixed versions: - commons-beanutils:commons-beanutils (Maven): affected from 1.8.0; fixed in 1.9.4 - commons-beanutils:commons-beanutils (Maven): affected from 1.8.0; fixed in 1.9.4 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
