AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Ullu app's parental PIN protection can be bypassed via brute force due to lack of rate-limiting, allowing unauthorized access to adult content.

An incorrect access control vulnerability exists in Ullu app (Android v2.9.929, iOS v2.8.0, and web platform) where the parental PIN feature lacks rate-limiting or lockout mechanisms. This allows attackers to brute-force the 4-digit PIN and bypass parental controls [1].

For the web version, attackers can capture the HTTP request sent when entering a PIN and automate brute-force attempts using tools like Burp Intruder. For mobile apps, the PIN can be brute-forced locally, either manually or via tools like Frida, by intercepting PIN entry attempts [1].

Successful exploitation disables the parental lock, granting unauthorized users unrestricted access to adult content. This escalates privileges and violates content accessibility protections, posing legal and compliance risks for age-restricted content delivery [1].

No official patch or mitigation has been disclosed. Vendors should implement rate-limiting and account lockout to prevent brute-force attacks on the PIN feature.
