CVE-2023-37473:
PHP vulnerability analysis and mitigation
Overview
CVE-2023-37473 affects zenstruck/collections, a set of helpers for iterating/paginating/filtering collections. The vulnerability was discovered and disclosed on July 14, 2023. The issue involves passing callable strings (like 'system') to EntityRepository::find() or query() functions, which could result in the execution of specific user input as code (GitHub Advisory).
Technical details
The vulnerability stems from insufficient validation of callable strings in the EntityRepository component. When callable strings were passed to the find() or query() functions, they would be executed as code. The vulnerability has a CVSS v3.1 Base Score of 8.8 (HIGH) with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating high severity with potential for significant impact (NVD).
Impact
The vulnerability allows a limited subset of user input to be executed as if it were code. This could potentially lead to unauthorized code execution within the application context, compromising the security of systems using the affected versions of zenstruck/collections (GitHub Advisory).
Mitigation and workarounds
The vulnerability has been addressed in version 0.2.1 with commit f4b1c48820. Users are strongly advised to upgrade to this version. For those unable to upgrade immediately, the recommended workaround is to ensure that user input is not passed to either EntityRepository::find() or query() functions (GitHub Advisory).
