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

To mitigate CVE-2025-15437, organizations should immediately upgrade LigeroSmart installations to version 6.1.26 or 6.3, where the vulnerability has been patched. In addition to patching, administrators should implement web application firewalls (WAFs) with rules designed to detect and block malicious payloads targeting the REQUEST_URI parameter. Security teams should conduct user awareness training to reduce the risk of users clicking on suspicious links. Employing Content Security Policy (CSP) headers can help limit the impact of XSS by restricting the execution of unauthorized scripts. Regularly audit and monitor web server logs for unusual request patterns that may indicate exploitation attempts. If immediate patching is not feasible, consider temporarily disabling or restricting access to the vulnerable component or applying input validation controls at the network edge. Finally, ensure that session management mechanisms use secure, HttpOnly cookies to reduce the risk of session hijacking.

Description

A vulnerability was found in LigeroSmart up to 6.1.24. This affects an unknown part of the component Environment Variable Handler. Performing a manipulation of the argument REQUEST_URI results in cross site scripting. The attack may be initiated remotely. The exploit has been made public and could be used. Upgrading to version 6.1.26 and 6.3 is able to mitigate this issue. The patch is named 264ac5b2be5b3c673ebd8cb862e673f5d300d9a7. The affected component should be upgraded.

Impact

The primary impact of CVE-2025-15437 is on the confidentiality and integrity of user sessions within LigeroSmart deployments. Successful exploitation can lead to the execution of arbitrary scripts in the context of authenticated users, enabling attackers to steal session cookies, perform actions on behalf of users, or deliver phishing payloads. This can result in unauthorized access to sensitive organizational data or manipulation of business processes managed through LigeroSmart. While the vulnerability does not directly compromise server availability or system-level integrity, the indirect effects of compromised user accounts can be significant. Organizations relying on LigeroSmart for critical operations may face reputational damage, data breaches, or regulatory compliance issues if exploited. The ease of remote exploitation without authentication increases the threat surface, especially in environments where users may be tricked into clicking malicious links. However, the requirement for user interaction and the lack of privilege escalation limit the overall severity compared to more critical vulnerabilities.

Summary

CVE-2025-15437 is a cross-site scripting vulnerability identified in LigeroSmart, a software product used for business or organizational management. The flaw exists in the Environment Variable Handler component, where the REQUEST_URI parameter is not properly sanitized or validated. This allows an attacker to craft a malicious URL that, when visited by a user, executes arbitrary JavaScript in the context of the victim's browser. The vulnerability is remotely exploitable without requiring authentication, but it does require user interaction, such as clicking a malicious link. The attack vector is network-based with low complexity, and no privileges are needed to launch the attack. The impact primarily affects the victim's browser session, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of the user. The vulnerability affects all LigeroSmart versions from 6.1.0 through 6.1.24. The vendor has released patches in versions 6.1.26 and 6.3, which address the issue by properly sanitizing the REQUEST_URI input. Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation. The CVSS 4.0 vector indicates a medium severity with a score of 5.1, reflecting the vulnerability's moderate impact and ease of exploitation.
