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

Given the absence of an official patch, organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and sanitization on the 'Profile' parameter at the web application firewall (WAF) or reverse proxy level to block malicious payloads; 2) Implementing Content Security Policy (CSP) headers to restrict script execution and mitigate impact of injected scripts; 3) Restricting access to the /otrs/index.pl?Action=AgentTicketSearch endpoint to trusted internal networks or authenticated users only; 4) Educating users to avoid clicking suspicious links and reporting unusual application behavior; 5) Monitoring logs for unusual requests targeting the vulnerable parameter; 6) Planning and prioritizing upgrade or patch deployment once LigeroSmart releases a fix; 7) Considering temporary disabling or limiting the vulnerable functionality if feasible. These steps reduce attack surface and limit exploitation opportunities until a permanent fix is available.

Description

A weakness has been identified in LigeroSmart up to 6.1.26. Impacted is an unknown function of the file /otrs/index.pl?Action=AgentTicketSearch. This manipulation of the argument Profile causes cross site scripting. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

Impact

The primary impact of this XSS vulnerability is the potential compromise of user sessions and credentials, which can lead to unauthorized access to sensitive ticketing and customer support data. Attackers can leverage this to impersonate legitimate users, escalate privileges, or conduct further attacks such as phishing or malware distribution within the affected organization's network. Since LigeroSmart is often used in enterprise environments for managing support tickets and internal communications, exploitation could disrupt business operations and damage organizational reputation. The medium severity score reflects the moderate ease of exploitation combined with the need for user interaction. However, the public availability of exploit code increases the likelihood of opportunistic attacks. Organizations without timely mitigation may face data breaches, loss of customer trust, and compliance violations, especially in regulated industries. The lack of an official patch prolongs exposure and complicates risk management.

Summary

CVE-2026-2545 identifies a cross-site scripting (XSS) vulnerability in LigeroSmart, a ticketing and customer support platform, affecting all versions up to 6.1.26. The vulnerability resides in the /otrs/index.pl script, specifically when handling the 'Profile' parameter in the AgentTicketSearch action. An attacker can craft malicious input to this parameter, which is then improperly sanitized or encoded, allowing the injection and execution of arbitrary JavaScript in the context of a legitimate user's browser session. This flaw is remotely exploitable without authentication, though it requires the victim to interact with a crafted link or page to trigger the payload. The vulnerability has been publicly disclosed with exploit code available, increasing the risk of exploitation. LigeroSmart developers have been notified but have not yet released a patch or official fix. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity by enabling session hijacking, credential theft, or unauthorized actions performed via the victim's browser. Availability impact is minimal. The vulnerability is present across a wide range of versions, making many deployments susceptible. No mitigations or patches have been officially published, leaving organizations reliant on internal controls or temporary workarounds.
