How to Fix CVE-2023-24622

To remediate this vulnerability, upgrade all affected Safeurl python dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

safeurl-python fixed: 1.2 
pip install safeurl-python>=1.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show safeurl-python

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-24622, inspect your installed packages using pip:

pip show safeurl-python

Analyze the terminal output to locate any version of Safeurl python in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2), your application is affected.

Note: The pip show safeurl-python command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Safeurl python, 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.

Source Advisory Statement

### Description In SafeURL it is possible to specify a list of domains that should be matched before a request is sent out. The regex used to compare domains did not work as intended. ### Impact The regex used was: `re.match("(?i)^%s" % domain, value)` This has two problems, first that only the beginning and not the end of the string is anchored. Second, that a dot in the domain matches any character as part of regex syntax. Therefore, an allowlist of ["victim.com"] could allow the domain "victimacomattacker.com" to be requested. This has lower impact since the usual attacker aim in an SSRF is to request internal resources such as private IP addresses rather than an attacker's own domain. But, in a case where SafeURL had specifically been used to try to limit requests to a particular allowlist, say for example a PDF renderer, the finding would be more severe. ### Patches Fixed in https://github.com/IncludeSecurity/safeurl-python/pull/5 ### References [Server-side request forgery (SSRF)](https://portswigger.net/web-security/ssrf)
