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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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 impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), 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 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 CVE-2025-20307, organizations should immediately apply Cisco’s official patches or updates addressing this vulnerability for their specific BroadWorks versions. Beyond patching, strict access controls must be enforced on the management interface, including limiting access to trusted networks and using multi-factor authentication to reduce the risk of credential compromise. Administrators should be trained to recognize phishing attempts and avoid interacting with suspicious links that could trigger XSS payloads. Implementing Content Security Policy (CSP) headers on the management interface can help restrict the execution of unauthorized scripts. Regular security audits and monitoring of administrative sessions for unusual activity can detect potential exploitation attempts early. Additionally, segregating management interfaces from general user networks and employing network-level protections such as Web Application Firewalls (WAFs) configured to detect XSS patterns can provide an additional defense layer. Organizations should also review and sanitize all user inputs in custom integrations or extensions to the BroadWorks interface to prevent similar vulnerabilities.

Description

A vulnerability in the web-based management interface of Cisco BroadWorks CommPilot Application Software could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid administrative credentials.

Impact

The primary impact of CVE-2025-20307 is the potential compromise of administrative sessions and exposure of sensitive information within the Cisco BroadWorks management interface. An attacker exploiting this XSS vulnerability could execute arbitrary JavaScript in the context of an authenticated administrator’s browser, leading to session hijacking, unauthorized configuration changes, or data theft. This could undermine the integrity and confidentiality of the telephony system’s management, potentially disrupting service configurations or exposing sensitive customer or operational data. Although availability is not directly affected, the indirect consequences of compromised administrative control could lead to service degradation or outages. Given the extensive use of Cisco BroadWorks in telecommunications and enterprise unified communications, exploitation could have cascading effects on communication reliability and security. The requirement for valid credentials and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, especially in environments with weak access controls or phishing risks. Organizations globally that rely on Cisco BroadWorks for critical communications could face operational and reputational damage if this vulnerability is exploited.
