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

Exploitation evidence

Disclosed: evidence found.
CVE published 31 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.

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

No attack traffic recorded by OffSeq Mirage sensors

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 CVE-2025-15373, organizations should promptly upgrade EyouCMS to version 1.7.8 once it is released, as this will contain the official patch addressing the SSRF vulnerability. If you cannot patch yet, administrators should consider implementing network-level controls such as firewall rules to restrict outbound HTTP requests from the web server hosting EyouCMS, limiting the server's ability to reach internal or sensitive endpoints. Additionally, input validation and sanitization should be reviewed and enhanced in the saveRemote function or equivalent code paths to ensure that user-supplied URLs are strictly validated against an allowlist of trusted domains or IP addresses. Employing web application firewalls (WAFs) with SSRF detection rules can provide temporary protection by blocking suspicious request patterns. Monitoring logs for unusual outbound requests originating from the EyouCMS server can help detect exploitation attempts early. Finally, conducting a thorough internal network segmentation review to minimize the exposure of critical services to the CMS server will reduce the potential impact of SSRF exploitation.

Description

A security vulnerability has been detected in EyouCMS up to 1.7.7. Impacted is the function saveRemote of the file application/function.php. Such manipulation leads to server-side request forgery. It is possible to launch the attack remotely. The exploit has been disclosed publicly 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 SSRF vulnerability in EyouCMS can have significant impacts on organizations using the affected versions. Attackers can leverage this flaw to perform unauthorized internal network reconnaissance, potentially accessing sensitive internal services that are not exposed externally. This can lead to information disclosure, such as accessing internal APIs, metadata services, or administrative interfaces. Additionally, SSRF can be a stepping stone for further exploitation, including lateral movement within the network or launching attacks against other internal systems. While the direct impact on data integrity or availability is limited, the ability to reach otherwise inaccessible resources poses a substantial security risk. Organizations hosting sensitive data or critical infrastructure behind EyouCMS installations are particularly at risk. The medium CVSS score reflects the moderate but non-trivial risk, especially given the ease of remote exploitation without authentication. Failure to address this vulnerability could result in data breaches, compliance violations, and reputational damage.
