CVE-2023-52028
RCE in Totolink A3700R Firmware 9.1.2u.5822_b20200513
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-52028 is a critical-severity OS Command Injection (CWE-78) vulnerability in Totolink A3700R Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 24% 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.
TOTOlink A3700R firmware version 9.1.2u.5822_B20200513 contains a remote command execution vulnerability in the setTracerouteCfg function. The flaw is an instance of OS command injection (CWE-78) that permits unauthenticated attackers to supply crafted input leading to arbitrary command execution on the device. It carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low complexity, and no required privileges or user interaction.
An attacker with network reachability to the router can invoke setTracerouteCfg over the web interface or related endpoints and execute operating-system commands with the privileges of the web server process. Successful exploitation yields full control over the device, enabling actions such as configuration changes, traffic interception, persistence, or use as an internal network pivot.
The associated EPSS score stands at 0.2055 with an identical recorded peak, indicating sustained but not sharply increasing exploitation interest since disclosure. Public technical write-ups detail the injection vector but provide no information on vendor patches or official mitigation steps.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
