CVE-2024-26293 in NEXIS E-series
Summary
by MITRE • 07/14/2025
The Avid Nexis Agent uses a vulnerable gSOAP version. An undocumented vulnerability impacting gSOAP v2.8 makes the application vulnerable to an Unauthenticated Path Traversal vulnerability. This issue affects Avid NEXIS E-series: before 2025.5.1; Avid NEXIS F-series: before 2025.5.1; Avid NEXIS PRO+: before 2025.5.1; System Director Appliance (SDA+): before 2025.5.1.

The vulnerability CVE-2024-26293 represents a critical security flaw in Avid Nexis systems that stems from the use of an outdated gSOAP version within the Avid Nexis Agent component. This issue manifests as an unauthenticated path traversal vulnerability that exploits a previously undocumented weakness in gSOAP version 2.8. The affected systems include multiple product lines within the Avid Nexis ecosystem, specifically the E-series, F-series, and PRO+ models, along with the System Director Appliance, all prior to version 2025.5.1. The vulnerability's presence in the gSOAP library creates a fundamental security gap that allows unauthorized attackers to manipulate file paths and potentially access restricted system resources without proper authentication credentials.
The technical exploitation of this vulnerability occurs through the gSOAP web services framework that Avid Nexis employs for communication between system components. When the Avid Nexis Agent processes incoming requests, it fails to properly validate or sanitize file path inputs, allowing attackers to craft malicious requests that traverse directory structures beyond the intended application boundaries. This path traversal capability enables adversaries to access sensitive files, configuration data, or system resources that should remain protected. The vulnerability operates at the application layer and can be exploited remotely, making it particularly dangerous as it does not require any prior authentication or privileged access to the system. The gSOAP library's inadequate input validation mechanisms create an attack surface that allows for arbitrary file access and potential system compromise.
The operational impact of this vulnerability extends beyond simple unauthorized file access, as it could enable attackers to gain deeper system insights and potentially escalate privileges within the Avid Nexis environment. Security researchers have identified this weakness as particularly concerning because it affects critical infrastructure components used in professional media production environments where system integrity and data security are paramount. The vulnerability's unauthenticated nature means that any external attacker with network access to the affected systems could exploit it, potentially leading to data breaches, system disruption, or unauthorized modification of critical media workflows. Organizations using affected Avid Nexis systems face significant risk of unauthorized access to sensitive production data, system configuration files, and potentially the complete compromise of their media infrastructure.
Organizations should immediately implement mitigations including updating to the patched versions of Avid Nexis software released in the 2025.5.1 update cycle for all affected product lines. The vulnerability aligns with CWE-22 Path Traversal and CWE-79 Improper Neutralization of Special Elements used in an OS Command, representing a significant risk to system integrity and data security. Security teams should also consider implementing network segmentation, firewall rules to restrict access to affected systems, and monitoring for unusual file access patterns that might indicate exploitation attempts. Additionally, the vulnerability demonstrates the importance of regular third-party library updates and security audits, as it highlights how outdated components within application stacks can create persistent security weaknesses that may remain undetected for extended periods. This case represents a typical ATT&CK technique involving path traversal for initial access and privilege escalation, emphasizing the need for robust input validation and secure coding practices in enterprise software deployments.
