The CVE-2022-27463 vulnerability represents a critical open redirect flaw discovered in the WWBN AVideo platform version 11.6 and earlier. This security weakness exists within the objects/login.json.php component of the application, creating a pathway for malicious actors to manipulate user navigation through carefully crafted URLs. The vulnerability specifically enables attackers to redirect users from legitimate website pages to the application's login page, potentially facilitating phishing attacks and social engineering campaigns. The flaw stems from insufficient input validation and sanitization of redirect parameters, allowing unauthorized redirections that can deceive users into believing they are navigating to trusted destinations while actually being directed to attacker-controlled login interfaces.
This vulnerability operates as an open redirect vulnerability, classified under CWE-601, which occurs when an application redirects users to external sites without proper validation of the destination URL. The technical implementation flaw lies in how the application processes redirect parameters in the login.json.php endpoint, failing to verify that the target URL belongs to the legitimate domain or application. Attackers can exploit this by constructing malicious URLs containing redirect parameters that point to their own domains, thereby capturing user credentials or conducting further malicious activities. The vulnerability's impact extends beyond simple redirection since it can be chained with other attacks such as credential harvesting or session hijacking, making it particularly dangerous in enterprise environments where user trust and authentication security are paramount.
The operational impact of CVE-2022-27463 is significant for organizations using WWBN AVideo platforms, as it undermines user trust and creates potential entry points for more sophisticated attacks. When users encounter phishing attempts that appear legitimate due to the application's redirect behavior, they may unknowingly provide credentials to malicious actors. This vulnerability can be exploited in various attack scenarios including spear-phishing campaigns, where attackers craft convincing URLs that redirect users to fake login pages designed to capture authentication information. The attack vector aligns with techniques documented in the MITRE ATT&CK framework under T1566 for credential harvesting and T1531 for use of stolen credentials, demonstrating how this vulnerability can serve as a gateway for broader compromise attempts.
Organizations utilizing affected versions of WWBN AVideo should implement immediate mitigations to address this vulnerability. The primary remediation involves validating and sanitizing all redirect parameters before processing them, ensuring that only URLs originating from the legitimate application domain are accepted. Implementing a whitelist approach for redirect destinations or using a secure redirect mechanism that verifies the target URL against a trusted domain list provides effective protection against unauthorized redirections. Additionally, security teams should monitor application logs for suspicious redirect patterns and implement web application firewalls that can detect and block malicious redirect attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar issues in other components of the platform, while users should be educated about recognizing potential phishing attempts and the importance of verifying URLs before entering credentials. The vulnerability highlights the critical importance of proper input validation and secure coding practices in preventing open redirect scenarios that can compromise user security and application integrity.
