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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within 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

Exploitation evidence

CVE published 14 Jul 2025

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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

To mitigate this vulnerability, European organizations should first verify if Sapido RB-1802 routers version 1.0.32 are deployed within their environment. If so, immediate steps include restricting access to the router's management interface to trusted networks only, preferably via VPN or secure management channels. Implement strict input validation and sanitization on the URL Filtering Page if custom firmware or configurations are possible. Monitor network traffic for unusual patterns that may indicate exploitation attempts. Additionally, educating network administrators about the risks of interacting with suspicious URLs and enforcing multi-factor authentication for router management interfaces can reduce exploitation likelihood. Regularly auditing router configurations and applying network segmentation to isolate management interfaces from general user access will further limit exposure. Finally, deploying web application firewalls (WAFs) or intrusion detection systems (IDS) capable of detecting XSS attempts targeting router interfaces can provide an additional security layer.

Description

A vulnerability classified as problematic was found in Sapido RB-1802 1.0.32. This vulnerability affects unknown code of the file urlfilter.asp of the component URL Filtering Page. The manipulation of the argument URL address leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations, the impact of this vulnerability depends largely on the deployment of the Sapido RB-1802 routers within their network infrastructure. If these routers are used in enterprise or critical infrastructure environments, successful exploitation could lead to unauthorized access to router management interfaces, enabling attackers to manipulate network traffic or gain further footholds. The XSS vulnerability primarily threatens the integrity of user sessions and could facilitate phishing or social engineering attacks targeting network administrators. While the direct impact on confidentiality and availability is limited, the indirect consequences could be significant if attackers leverage this vulnerability to escalate privileges or pivot within the network. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks if such vulnerabilities are exploited. Moreover, since the attack vector is remote, attackers can target exposed management interfaces accessible from the internet, increasing the risk for organizations with insufficient network segmentation or firewall protections.
