CVE-2014-2744

High
Published: Translated: NVD NIST

Summary

The mod_compression.lua plugin in Prosody before version 0.9.4 and Lightwitch Metronome through version 3.4 negotiates stream compression while a session is unauthenticated. This allows remote attackers to cause a denial of service via compressed XML elements in an XMPP stream, known as an 'xmppbomb' attack.

Risk Assessment

Attackers can exploit this vulnerability to exhaust server resources, leading to denial of service for users. This can significantly impact the availability of XMPP services within the organization.

Recommendation

It is recommended to update Prosody to version 0.9.4 or later and Lightwitch Metronome to version 3.4 or later to mitigate this vulnerability. Additionally, consider implementing authentication mechanisms before negotiating stream compression.
