CVE-2024-52012 is a medium-severity Relative Path Traversal (CWE-23) vulnerability in Apache Solr. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-52012 is a relative path traversal vulnerability, also known as ZipSlip, that affects the configset upload API in Apache Solr versions 6.6 through 9.7.0 when running on Windows. The flaw stems from insufficient input sanitization, allowing maliciously crafted ZIP archives to specify relative file paths that result in arbitrary writes outside the intended directory on the filesystem.
An attacker with access to the configset upload API can exploit the issue to write files to arbitrary locations on the Windows host. With a CVSS score of 5.4, the vulnerability requires low-privileged network access and can lead to limited impacts on confidentiality and integrity without affecting availability.
Apache Solr advisories recommend upgrading to version 9.8.0 to resolve the issue. Organizations unable to upgrade can mitigate exposure by enabling the Rule-Based Authentication Plugin to restrict the configset upload API to trusted administrators only. The associated EPSS score has remained essentially flat near 0.14 with no material increase after disclosure.

Vulnerability Data
Relative Path Traversal vulnerability in Apache Solr. Solr instances running on Windows are vulnerable to arbitrary filepath write-access, due to a lack of input-sanitation in the "configset upload" API. Commonly known as a "zipslip", maliciously constructed ZIP files can use…

relative filepaths to write data to unanticipated parts of the filesystem. This issue affects Apache Solr: from 6.6 through 9.7.0. Users are recommended to upgrade to version 9.8.0, which fixes the issue. Users unable to upgrade may also safely prevent the issue by using Solr's "Rule-Based Authentication Plugin" to restrict access to the configset upload API, so that it can only be accessed by a trusted set of administrators/users.

Mitigating Controls (NIST 800-53 r5) AI
Explicit validation of path inputs stops .. sequences from ever being interpreted by the file system.
Access enforcement directly blocks unauthorized file reads/writes that result from unresolved .. sequences.
Information-flow rules can be configured to reject traversals that would move data outside an approved directory boundary.
Least privilege reduces the set of reachable files even when a traversal succeeds.
Secure-engineering principles require safe pathname construction and input neutralization before any file operation.

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.
Secure development lifecycle mandates input validation and path-handling controls that directly prevent relative path traversal.
Application security requirements explicitly call for controls against path traversal and other injection flaws.
Secure architecture principles include directory isolation and canonicalization, reducing but not eliminating traversal risk.
Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.
Information access restriction limits which files can be reached, mitigating impact but not preventing the traversal flaw.
