Published: 07 March 2024
Summary
CVE-2023-48725 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Netgear Rax30 Firmware. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 3.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A stack-based buffer overflow vulnerability exists in the JSON Parsing getblockschedule() functionality of Netgear RAX30 firmware versions 1.0.11.96 and 1.0.7.78. Tracked as CVE-2023-48725 with a CVSS 3.1 score of 7.2, the flaw stems from improper handling of crafted input and is also associated with CWE-121 and CWE-787. A specially crafted HTTP request can trigger memory corruption that leads to code execution.
An authenticated attacker with network access can exploit the issue by sending a malicious HTTP request to the affected device. Successful exploitation grants the attacker the ability to execute arbitrary code with full impact on confidentiality, integrity, and availability.
Netgear has published a security advisory for the post-authentication stack overflow on the RAX30 (PSV-2023-0160) that is referenced alongside detailed technical analysis from Talos Intelligence.
The EPSS score remains near 0.32 with no material change between its recorded peak and current value.
