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, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can discover stack-buffer overflows before deployment.

Input validation directly stops untrusted data from exceeding stack buffer bounds.

Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

Secure-engineering principles include bounds-checked coding and safe buffer handling that avoid introducing the flaw.
