Deeper analysis
A stack overflow vulnerability, tracked as CVE-2023-27077 and assigned CWE-787, affects the 360 D901 device. The flaw resides in HTTP request handling and permits an unauthenticated remote attacker to supply a specially crafted packet that triggers memory corruption, resulting in a denial-of-service condition with high impact on availability.
An attacker with network access can exploit the issue without credentials or user interaction by sending the malicious HTTP packet to the affected device. Successful exploitation causes the target to crash or become unresponsive, producing the reported distributed denial-of-service outcome.
The EPSS score for the CVE rose from a low baseline to a peak of 0.0529 before receding to its current value of 0.0334, indicating a measurable but temporary increase in observed exploitation interest after public disclosure.
