How to Fix CVE-2023-51651
To remediate this vulnerability, upgrade all affected Aws/aws sdk php dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade aws/aws-sdk-php to 3.288.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for aws/aws-sdk-phpHow to Check if You Are Affected
To determine whether your application is affected by CVE-2023-51651, inspect your project dependencies for Aws/aws sdk php:
inspect dependencies for aws/aws-sdk-phpAnalyze the terminal output to locate any version of Aws/aws sdk php in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.288.1), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Aws/aws sdk php, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\nWithin the scope of requests to S3 object keys and/or prefixes containing a Unix double-dot, a URI path traversal is possible. The issue exists in the`buildEndpoint` method in the `RestSerializer` component of the AWS SDK for PHP v3 prior to 3.288.1. The `buildEndpoint` method relies on the Guzzle Psr7 `UriResolver` utility, which strips dot segments from the request path in accordance with RFC 3986. Under certain conditions, this could lead to an arbitrary object being accessed.\n\nVersions of the AWS SDK for PHP v3 before 3.288.1 are affected by this issue.\n\n### Patches\nUpgrade to the AWS SDK for PHP >= 3.288.1, if you are on version < 3.288.1.\n\n### References\nRFC 3986 - [https://datatracker.ietf.org/doc/html/rfc3986](https://datatracker.ietf.org/doc/html/rfc3986#section-5.2.4)\n\n### For more information\nIf you have any questions or comments about this advisory, please contact [AWS's Security team](mailto:aws-security@amazon.com).",
