CVE-2022-25336

When image files are uploaded, they are made accessible under a name similar to the original file name. There are two issues with this. Both require access to uploading images in order to exploit them, this limits the impact. The first issue is that certain injection attacks can be possible, since not all possible attack vectors are removed from the original file name.

The second issue is that direct access to the images is not access controlled. This is by design, for performance reasons, and documented as such. But it does mean that images not meant to be publicly accessible can be accessed, provided that the image path and filename is correctly deduced and/or guessed, through dictionary attacks and similar.

CVE-2022-25336 has a CVSS score of 5.3 (Medium). 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 (1.3.12); upgrading removes the vulnerable code path.

1. What is CVE-2022-25336? CVE-2022-25336 is a medium-severity security vulnerability in ezsystems/ezplatform-kernel (composer), affecting versions >= 1.3.0, < 1.3.12. It is fixed in 1.3.12.
2. How severe is CVE-2022-25336? CVE-2022-25336 has a CVSS score of 5.3 (Medium). 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.
3. Which versions of ezsystems/ezplatform-kernel are affected by CVE-2022-25336? ezsystems/ezplatform-kernel (composer) versions >= 1.3.0, < 1.3.12 is affected.
4. Is there a fix for CVE-2022-25336? Yes. CVE-2022-25336 is fixed in 1.3.12. Upgrade to this version or later.
5. Is CVE-2022-25336 exploitable, and should I be worried? Whether CVE-2022-25336 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.

6. What actually determines whether CVE-2022-25336 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.
7. How do I fix CVE-2022-25336? Upgrade ezsystems/ezplatform-kernel to 1.3.12 or later.
