How to Fix CVE-2017-5591

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

slixmpp fixed: 1.2.4 
pip install slixmpp>=1.2.4
SleekXMPP fixed: 1.3.2 
pip install SleekXMPP>=1.3.2
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 slixmpp

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-5591, inspect your installed packages using pip:

pip show slixmpp

Analyze the terminal output to locate any version of Slixmpp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.4), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-940: Improper Verification of Source of a Communication Channel, where the product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin. In Slixmpp, 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

An incorrect implementation of "XEP-0280: Message Carbons" in multiple XMPP clients allows a remote attacker to impersonate any user, including contacts, in the vulnerable application's display. This allows for various kinds of social engineering attacks. This CVE is for SleekXMPP up to 1.3.1 and Slixmpp all versions up to 1.2.3, as bundled in poezio (0.8 - 0.10) and other products.
