CVE-2023-49810 is a vulnerability classified under CWE-307 (Improper Restriction of Excessive Authentication Attempts) affecting the WWBN AVideo platform, specifically in the dev master commit 15fed957fb. The vulnerability resides in the checkLoginAttempts functionality, which is intended to limit the number of login attempts to prevent brute force attacks. However, due to improper implementation, an attacker can craft specific HTTP requests that bypass CAPTCHA challenges designed to mitigate automated login attempts. This bypass allows an attacker to send numerous login requests without being blocked or challenged, effectively enabling brute force attacks against user credentials. The vulnerability does not require any prior authentication or user interaction, making it remotely exploitable over the network. The CVSS v3.1 score of 7.3 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges or user interaction required. Although no public exploits have been reported yet, the vulnerability presents a significant risk to systems running the affected AVideo version, potentially leading to unauthorized access, data leakage, or service disruption.

For European organizations, this vulnerability poses a considerable threat, especially those utilizing WWBN AVideo for video content delivery, education, or corporate communications. Successful exploitation can lead to unauthorized access to user accounts, potentially exposing sensitive personal or corporate data. The ability to bypass CAPTCHA and brute force credentials increases the risk of account takeover, which can be leveraged for further lateral movement or data exfiltration. Additionally, repeated brute force attempts may degrade service availability or trigger denial-of-service conditions. Given the increasing reliance on video platforms for remote work and digital engagement in Europe, the impact extends to operational disruption and reputational damage. Organizations in sectors such as media, education, and government that deploy AVideo are particularly vulnerable. The lack of known exploits in the wild suggests an opportunity for proactive mitigation before widespread attacks occur.

1. Monitor WWBN's official channels for patches addressing CVE-2023-49810 and apply them immediately upon release. 2. In the interim, implement additional rate-limiting controls at the web server or application firewall level to restrict the number of login attempts per IP address or user account. 3. Deploy multi-factor authentication (MFA) to add an extra layer of security beyond passwords. 4. Enhance logging and monitoring of login attempts to detect unusual patterns indicative of brute force attacks. 5. Consider deploying web application firewalls (WAFs) with custom rules to detect and block requests attempting to bypass CAPTCHA mechanisms. 6. Educate users about strong password practices and encourage regular password updates. 7. Conduct regular security assessments and penetration tests focusing on authentication mechanisms. 8. If feasible, isolate or restrict access to AVideo administrative interfaces to trusted networks or VPNs to reduce exposure.
