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: 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), 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

Upgrade EyouCMS to version 1.7.8 immediately upon its release, as it contains the official patch addressing this vulnerability.
Until the patch is available, implement strict input validation and output encoding on the 'content' parameter within the Ask module to neutralize malicious scripts.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers.
Review and sanitize all user-generated content before rendering it on web pages.
Monitor web server logs and application logs for suspicious requests targeting the Ask module or containing suspicious payloads.
Educate users about the risks of clicking on untrusted links to reduce the likelihood of successful exploitation via social engineering.
Consider deploying Web Application Firewalls (WAFs) with rules to detect and block common XSS attack patterns targeting EyouCMS.
Conduct regular security assessments and penetration testing focusing on input validation and XSS vulnerabilities in the CMS environment.

Description

A vulnerability was detected in EyouCMS up to 1.7.7. The affected element is an unknown function of the file application/home/model/Ask.php of the component Ask Module. Performing a manipulation of the argument content results in cross site scripting. The attack can be initiated remotely. The exploit is now public and may be used. The vendor is "[a]cknowledging the existence of the vulnerability, we have completed the fix and will release a new version, v1.7.8".

Impact

The primary impact of CVE-2025-15374 is the compromise of user trust and security through cross-site scripting attacks. Attackers can execute arbitrary scripts in the context of authenticated users, potentially stealing session cookies, redirecting users to malicious sites, or performing unauthorized actions on behalf of users. For organizations, this can lead to data breaches, unauthorized access to sensitive information, defacement of websites, and erosion of customer confidence. Since EyouCMS is used to manage web content, exploitation could also facilitate further attacks such as malware distribution or phishing campaigns hosted on compromised sites. The medium severity rating indicates a moderate risk, but the ease of remote exploitation without authentication and the public availability of exploit information elevate the urgency for remediation. Organizations with public-facing EyouCMS installations are particularly at risk, especially if they have high user interaction or rely on the Ask module for user-generated content.

Summary

CVE-2025-15374 identifies a cross-site scripting vulnerability in EyouCMS, a content management system, specifically within the Ask module's code located at application/home/model/Ask.php. The vulnerability arises from improper sanitization of the 'content' parameter, which an attacker can manipulate to inject arbitrary JavaScript code. This injection occurs because the application fails to adequately validate or encode user-supplied input before rendering it in the web interface. The vulnerability is remotely exploitable without requiring authentication, but successful exploitation depends on tricking a user into interacting with the malicious payload, such as clicking a crafted link or visiting a compromised page. The CVSS 4.0 base score of 5.1 reflects a medium severity, considering the network attack vector, low attack complexity, no privileges required, but requiring user interaction and limited impact on confidentiality and integrity. The vendor has acknowledged the issue and plans to release version 1.7.8 with a fix. No public exploits have been observed in the wild yet, but the disclosure and availability of technical details increase the risk of exploitation attempts. This vulnerability can be leveraged to execute scripts in the context of the victim's browser, potentially leading to session hijacking, credential theft, or unauthorized actions within the CMS environment.
