CVE-2022-32777 in AVideo
Summary
by MITRE • 08/22/2022
An information disclosure vulnerability exists in the cookie functionality of WWBN AVideo 11.6 and dev master commit 3f7c0364. The session cookie and the pass cookie miss the HttpOnly flag, making them accessible via JavaScript. The session cookie also misses the secure flag, which allows the session cookie to be leaked over non-HTTPS connections. This could allow an attacker to steal the session cookie via crafted HTTP requests.This vulnerabilty is for the session cookie which can be leaked via JavaScript.

The vulnerability described in CVE-2022-32777 represents a critical information disclosure flaw within the WWBN AVideo platform version 11.6 and its development branch. This security weakness specifically targets the cookie management functionality of the application, creating potential pathways for unauthorized access to user sessions. The vulnerability stems from improper cookie configuration that fails to implement essential security headers required for protecting sensitive session data. The affected system operates under the assumption that cookies containing session identifiers and authentication tokens should be protected from client-side script access, yet this protection mechanism is entirely absent from the implementation.
The technical flaw manifests through the absence of two critical HTTP cookie flags that are fundamental to web application security practices. The HttpOnly flag is missing from both the session cookie and the pass cookie, allowing JavaScript executed within the browser to access these sensitive cookies through document.cookie APIs. This violates the principle of least privilege and creates an attack surface where malicious scripts can harvest session tokens from legitimate user sessions. Additionally, the session cookie lacks the Secure flag implementation, which should prevent cookies from being transmitted over unencrypted HTTP connections. This omission enables man-in-the-middle attackers to intercept session cookies during transmission, particularly when users navigate to the application over insecure connections. The combination of these missing security flags creates a scenario where attackers can leverage cross-site scripting vulnerabilities or other client-side attack vectors to extract session identifiers.
The operational impact of this vulnerability extends beyond simple information disclosure, as it fundamentally undermines the authentication and session management mechanisms of the AVideo platform. An attacker who successfully exploits this vulnerability gains the ability to hijack user sessions, potentially accessing sensitive content, modifying user data, or performing unauthorized actions within the application. The vulnerability is particularly dangerous because it affects the core session management functionality, making it a prime target for session hijacking attacks. The fact that session cookies can be accessed via JavaScript means that even if the application itself does not directly expose these cookies, client-side attacks such as cross-site scripting can easily harvest them. This creates a significant risk for users who may be browsing the application over insecure networks or who encounter malicious websites that attempt to exploit this vulnerability through crafted payloads.
Security mitigation strategies for this vulnerability must focus on implementing proper cookie security headers across all session and authentication cookies within the application. The immediate fix involves adding the HttpOnly flag to all cookies that contain session identifiers or authentication tokens, preventing JavaScript access to these critical data elements. Additionally, the Secure flag must be implemented on session cookies to ensure they are only transmitted over encrypted HTTPS connections, thereby preventing interception over unencrypted channels. These changes align with established security standards including the CWE-16 category for "Improper Neutralization of Script-Related HTML Tags in a Web Page' and the OWASP Top Ten's A03:2021 category for 'Injection' vulnerabilities. Organizations should also consider implementing additional security measures such as SameSite cookie attributes to further protect against cross-site request forgery attacks. The remediation process should include comprehensive code review to ensure all cookie creation and management functions properly implement these security headers, with regular security testing to verify that the fixes remain effective. This vulnerability demonstrates the critical importance of following secure coding practices and implementing proper cookie security configurations as outlined in the ATT&CK framework's T1548.002 technique for 'Abuse Elevation Control Mechanism' which emphasizes the protection of session tokens from client-side manipulation.
