CVE-2022-32778 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 vulnerability is for the pass cookie, which contains the hashed password and can be leaked via JavaScript.

The vulnerability described in CVE-2022-32778 represents a critical information disclosure flaw within the WWBN AVideo platform version 11.6 and its development branch. This security weakness stems from improper implementation of cookie security attributes that directly impacts user authentication and session management. The vulnerability affects two distinct cookie types: the session cookie and the pass cookie, both of which are essential components for maintaining user authentication state and password security within the application.
The technical root cause of this vulnerability lies in the missing HttpOnly flag implementation for both the session cookie and pass cookie. According to CWE-1004, this represents a failure to properly configure security-sensitive cookies, which directly enables cross-site scripting attacks. The HttpOnly flag is a critical security mechanism that prevents client-side scripts from accessing cookie data, thereby mitigating the risk of session hijacking through malicious JavaScript execution. Additionally, the session cookie lacks the Secure flag, which is mandated by OWASP Top Ten and NIST guidelines for protecting sensitive session data. This absence allows the session cookie to be transmitted over unencrypted HTTP connections, creating an attack vector for man-in-the-middle and session hijacking techniques.
The operational impact of this vulnerability is severe and multifaceted. Attackers can leverage the missing HttpOnly flag to execute cross-site scripting attacks that extract both session and pass cookies from victim browsers through JavaScript execution. The pass cookie containing hashed passwords represents a particularly dangerous exposure since it provides attackers with authentication material that could potentially be reverse-engineered or used in credential stuffing attacks against other services. The combination of these vulnerabilities creates a pathway for unauthorized access to user accounts and sensitive system information. According to MITRE ATT&CK framework, this vulnerability maps to T1566 (Phishing) and T1531 (Account Access Removal) techniques, as attackers can use the stolen session tokens to impersonate legitimate users and gain unauthorized access to protected resources.
The security implications extend beyond simple session theft to encompass broader authentication bypass scenarios. The presence of the hashed password in the pass cookie creates additional attack surface for credential compromise, particularly when combined with other vulnerabilities or attack vectors. This vulnerability also violates fundamental security principles outlined in ISO/IEC 27001 and NIST SP 800-53, which mandate proper cookie configuration and secure session management practices. The missing Secure flag specifically contravenes security standards that require sensitive session data to be transmitted only over encrypted channels, making the system vulnerable to network-based attacks and eavesdropping.
Mitigation strategies should prioritize immediate implementation of the Secure and HttpOnly flags for all authentication-related cookies. Organizations should conduct comprehensive cookie security audits to identify and remediate similar vulnerabilities across their web applications. The fix requires configuration changes to ensure that session cookies include both the Secure flag to enforce HTTPS transmission and the HttpOnly flag to prevent JavaScript access. Additionally, implementing Content Security Policy (CSP) headers can provide additional protection against cross-site scripting attacks that might exploit this vulnerability. Regular security assessments and penetration testing should be conducted to validate the effectiveness of these mitigations and ensure compliance with security standards such as those defined in OWASP Web Security Testing Guide and NIST Cybersecurity Framework.
