Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Immediately disable remote management interfaces on Tenda AC7 routers to prevent external exploitation.
Restrict access to the router’s management interface to trusted internal IP addresses only, using firewall rules or access control lists.
Implement network segmentation to isolate vulnerable routers from critical internal systems and sensitive data.
Monitor network traffic for unusual patterns or connections indicative of exploitation attempts, such as unexpected command execution or outbound connections from the router.
Regularly audit router configurations and logs for signs of compromise or unauthorized changes.
Until an official patch is released, consider replacing affected routers with devices from vendors with a stronger security track record or that have issued timely patches.
Educate users and administrators about the risks of exposing router management interfaces to the internet.
Follow vendor channels closely for updates or firmware patches addressing this vulnerability and apply them promptly once available.
Employ intrusion detection/prevention systems capable of detecting command injection attempts targeting router management endpoints.
Use network-based anomaly detection tools to identify deviations from normal router behavior.

Description

A vulnerability was detected in Tenda AC7 15.03.06.44. This vulnerability affects unknown code of the file /goform/AdvSetLanip. The manipulation of the argument lanIp results in command injection. It is possible to launch the attack remotely. The exploit is now public and may be used.

Impact

The impact of CVE-2025-11523 on organizations worldwide can be significant, especially for those relying on Tenda AC7 routers in home, small office, or branch office environments. Successful exploitation allows remote attackers to execute arbitrary commands on the router, potentially leading to full device compromise. This can result in interception or manipulation of network traffic, unauthorized access to internal networks, disruption of internet connectivity, and use of the device as a pivot point for lateral movement or launching attacks against other targets. The compromise of network infrastructure devices undermines confidentiality, integrity, and availability of organizational data and services. Given the router’s role as a gateway, attackers could also deploy persistent backdoors or malware, complicating detection and remediation. The public availability of exploit code increases the likelihood of opportunistic attacks, including automated scanning and exploitation by botnets or cybercriminal groups. Organizations with limited IT security resources or lacking network segmentation are particularly vulnerable. The absence of patches exacerbates the risk, necessitating immediate mitigation to reduce exposure.

Summary

CVE-2025-11523 is a command injection vulnerability identified in the Tenda AC7 router firmware version 15.03.06.44. The vulnerability resides in an unspecified portion of the /goform/AdvSetLanip endpoint, specifically involving the lanIp parameter. By manipulating this parameter, an attacker can inject and execute arbitrary system commands on the router remotely. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), no privileges (PR:L) or user interaction (UI:N), and has partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability does not require authentication, making it accessible to remote attackers scanning for vulnerable devices. The exploit code is publicly available, increasing the risk of exploitation despite no current reports of active attacks. The router’s compromised state could allow attackers to intercept or redirect network traffic, deploy malware, or use the device as a foothold for further network intrusion. No official patches or vendor advisories have been published at the time of disclosure, leaving affected devices exposed. The vulnerability highlights the risks of insecure input validation in router management interfaces, a common attack surface in consumer and SMB networking equipment.
