Deeper analysis
CVE-2023-50239 affects the boa set_RadvdInterfaceParam functionality within Realtek rtl819x Jungle SDK version 3.4.11. The vulnerability consists of two stack-based buffer overflows, both tied to the interfacename parameter in specially crafted network requests, that can result in remote code execution. The issues are tracked under CWE-121 and CWE-787 and carry a CVSS 3.1 score of 7.2.
An attacker with high privileges who can reach the affected device over the network may send a sequence of requests to trigger the overflows and execute arbitrary code on the target.
The associated EPSS score rose from a low baseline to a peak of 0.1010 on 2025-12-11 before receding to its current value of 0.0731, indicating a measurable increase in observed exploitation interest after disclosure.
