Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-46123 is a high-severity Use of Externally-Controlled Format String (CWE-134) vulnerability in Ruckuswireless Ruckus Unleashed. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 38% 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.
The vulnerability is a format-string issue (CWE-134) affecting the authenticated configuration endpoint /admin/_conf.jsp in CommScope Ruckus Unleashed releases prior to 200.15.6.212.14 and 200.17.7.0.139, as well as Ruckus ZoneDirector releases prior to 10.5.1.0.279. The endpoint writes the Wi-Fi guest password to memory via snprintf, treating the attacker-supplied value directly as the format string and thereby enabling uncontrolled format-string processing that leads to remote code execution on the controller. The flaw carries a CVSS 3.1 base score of 7.2.
An authenticated administrator with network access can exploit the endpoint by submitting a crafted guest password value. Successful exploitation grants the attacker the ability to execute arbitrary code on the wireless controller, resulting in full compromise of confidentiality, integrity, and availability.
Vendor guidance published in the Ruckus security bulletin and the associated technical report directs administrators to upgrade Unleashed and ZoneDirector installations to the corrected releases that eliminate the unsafe snprintf usage.
The EPSS score stands at 0.0359 with no material change from its recorded peak.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and static analysis can discover format-string vulnerabilities before deployment.
Input validation can reject or sanitize externally supplied format strings before they reach formatting functions.
Secure development standards and tools can mandate use of static format strings or safe formatting APIs.

Security testing in development can detect format-string vulnerabilities before release.
Secure SDLC mandates input validation and safe API usage that can prevent externally-controlled format strings.
Application security requirements can specify safe formatting functions and ban uncontrolled format strings.
Secure architecture principles discourage dangerous string-handling patterns that lead to format-string issues.
Secure coding standards directly forbid the use of untrusted format strings and prescribe safe alternatives.
