CVE-2024-44080 in Meet
Summary
by MITRE • 10/30/2024
In Jitsi Meet before 2.0.9779, the functionality to share an image using giphy was implemented in an insecure way, resulting in clients loading GIFs from any arbitrary URL if a message from another participant contains a URL encoded in the expected format.

The vulnerability identified as CVE-2024-44080 affects Jitsi Meet versions prior to 2.0.9779 and represents a critical security flaw in the application's image sharing functionality. This issue specifically impacts the giphy integration feature where users can share animated GIFs during video conferences. The vulnerability stems from insufficient input validation and sanitization mechanisms within the client-side processing of URL-encoded content that is intended to be handled by the giphy service. When participants in a Jitsi Meet session send messages containing URL-encoded data formatted to match giphy's expected structure, the client application fails to properly validate the source or content of these URLs, creating an attack vector that allows malicious actors to inject arbitrary content.
The technical implementation flaw manifests in how Jitsi Meet processes URL-encoded parameters that are supposed to be restricted to giphy's domain and content type. When a user sends a message containing a properly formatted URL-encoded string, the application's client-side code does not adequately verify that the resulting GIF URL originates from legitimate giphy sources or that the content matches the expected parameters. This insecure implementation allows attackers to craft specially formatted messages that, when processed by other participants' clients, will load and display GIFs from any arbitrary web server, potentially including malicious content such as phishing pages, malware distribution sites, or content that could exploit browser vulnerabilities.
The operational impact of this vulnerability is significant within collaborative environments where Jitsi Meet is used for business meetings, educational sessions, or sensitive communications. An attacker who gains access to a conversation can potentially deliver cross-site scripting payloads, phishing content, or other malicious web resources to all participants in the meeting. The vulnerability essentially transforms the intended giphy functionality into a potential vector for remote code execution or data exfiltration through browser-based attacks. Given that many organizations rely on Jitsi Meet for secure communications, this vulnerability could be exploited to compromise the confidentiality and integrity of sensitive meetings and communications.
This vulnerability aligns with CWE-20, which covers "Improper Input Validation," and CWE-79, which addresses "Cross-site Scripting," as the insecure URL handling creates opportunities for both validation bypass and XSS exploitation. From an attack perspective, this flaw maps to techniques described in the MITRE ATT&CK framework under T1203, "Exploitation for Client Execution," and T1566, "Phishing," as it enables attackers to deliver malicious content through seemingly legitimate communication channels. The security implications extend beyond simple content delivery to potentially enable more sophisticated attacks including credential theft, session hijacking, or as a stepping stone for further compromise of the victim's systems.
Organizations using Jitsi Meet should immediately update to version 2.0.9779 or later to address this vulnerability. Additionally, administrators should implement network-level controls to monitor and restrict access to potentially malicious domains, though this represents a reactive measure rather than a complete fix. The recommended mitigation strategy involves comprehensive input validation and sanitization of all URL parameters, implementing strict domain whitelisting for external content sources, and employing content security policies that prevent loading of arbitrary resources from untrusted origins. Security teams should also consider implementing monitoring for unusual URL patterns in chat messages and establish incident response procedures for potential exploitation of this vulnerability during active meetings.
