It was observed that the /admin/misc/script-proxy API endpoint accessible by an authenticated administrator user and is vulnerable arbitrary JavaScript, CSS file read via the "scriptPath" and "scripts" parameters. The "scriptPath" parameter is not sanitized properly and is vulnerable to path traversal attack. Any JavaScript/CSS file from the application server can be read by specifying sufficient number of "../" patterns to go out from the application webroot followed by path of the folder where the file is located in the "scriptPath" parameter and the file name in the "scripts" parameter. The JavaScript file is successfully read only if the web application has read access to it.

Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

CVE-2023-30852 has a CVSS score of 4.4 (Medium). The vector is network-reachable, high 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 (10.5.21); upgrading removes the vulnerable code path.

1. What is CVE-2023-30852? CVE-2023-30852 is a medium-severity path traversal vulnerability in pimcore/pimcore (composer), affecting versions < 10.5.21. It is fixed in 10.5.21. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
2. How severe is CVE-2023-30852? CVE-2023-30852 has a CVSS score of 4.4 (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 pimcore/pimcore are affected by CVE-2023-30852? pimcore/pimcore (composer) versions < 10.5.21 is affected.
4. Is there a fix for CVE-2023-30852? Yes. CVE-2023-30852 is fixed in 10.5.21. Upgrade to this version or later.
5. Is CVE-2023-30852 exploitable, and should I be worried? Whether CVE-2023-30852 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-2023-30852 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-2023-30852? Upgrade pimcore/pimcore to 10.5.21 or later.
