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

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 2026-10-26.

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

1. Immediate mitigation should include implementing strict input validation and output encoding on the 'Name' parameter within the /system/org/save endpoint to prevent script injection. 2. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting this endpoint. 3. Restrict access to the Add Department Handler functionality to trusted users and enforce least privilege principles to minimize the risk associated with PR:H requirement. 4. Educate users about phishing and social engineering risks to reduce the chance of successful user interaction exploitation. 5. Monitor web server logs and application behavior for unusual requests or error patterns related to the vulnerable endpoint. 6. Coordinate with westboy for timely patch deployment once available and plan for immediate update. 7. Consider isolating or limiting exposure of the affected CMS instance from public internet access where feasible.

Description

A vulnerability was determined in westboy CicadasCMS 1.0. Affected by this issue is some unknown functionality of the file /system/org/save of the component Add Department Handler. This manipulation of the argument Name causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.

Impact

For European organizations using CicadasCMS version 1.0, this vulnerability could lead to unauthorized script execution in the context of the affected web application. This may result in theft of session tokens, redirection to malicious sites, or unauthorized actions performed on behalf of legitimate users. Given that CicadasCMS is a content management system, exploitation could compromise the integrity of published content, damage organizational reputation, and potentially expose sensitive internal information. The medium CVSS score reflects moderate risk, but the requirement for user interaction and some privilege level reduces the likelihood of widespread automated exploitation. However, targeted attacks against organizations relying on CicadasCMS could disrupt business operations or lead to data breaches. The lack of patches increases exposure time, emphasizing the need for immediate mitigation. European organizations in sectors with high regulatory requirements (e.g., finance, healthcare, government) could face compliance risks if this vulnerability is exploited.

Summary

CVE-2025-11069 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of westboy's CicadasCMS, specifically within the Add Department Handler component located at the /system/org/save endpoint. The vulnerability arises from improper sanitization or validation of the 'Name' argument, allowing an attacker to inject malicious scripts. This flaw can be exploited remotely without requiring authentication, although user interaction is necessary to trigger the malicious payload (e.g., a victim clicking a crafted link). The vulnerability has a CVSS 4.8 score, indicating a medium severity level. The attack vector is network-based (remote), with low attack complexity, but requires user interaction and privileges (PR:H) for exploitation, which suggests some level of access or authenticated session might be needed. The impact primarily affects the confidentiality and integrity of user sessions or data accessible via the CMS interface, potentially enabling session hijacking, defacement, or phishing attacks within the affected web application. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability disclosure date is September 27, 2025.
