A security vulnerability has been detected in LigeroSmart up to version 6.1.26. The affected element is an unknown function of the file /otrs/index.pl. Such manipulation of the argument TicketID leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
The CVSS score for this vulnerability is 2, indicating a low severity level. Risk to organizations includes potential unauthorized access to sensitive data through cross site scripting attacks. Given the nature of the vulnerability, organizations should prioritize patching immediately.
As of now, there are no known exploits for this vulnerability, and it has not been included in the Known Exploitable Vulnerabilities (KEV) catalog. However, the fact that it has been publicly disclosed means that organizations should not underestimate its risk potential.
In light of these factors, organizations utilizing LigeroSmart should assess their systems for this vulnerability and apply necessary updates to mitigate potential risks.
Vulnerability Details
The vulnerability in LigeroSmart allows for cross site scripting (XSS) due to improper handling of user input in the TicketID argument. The CVSS score, according to version 3.1, is rated at 5.4, classified as medium severity. The affected components are all versions of LigeroSmart up to 6.1.26, as indicated in the provided CPE information.
The issue has been classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code). The vulnerability was published on January 17, 2026, and has been analyzed but is currently awaiting a patch from the vendor.
Technical Analysis
The root cause of this vulnerability relates to improper input validation in the TicketID parameter of the /otrs/index.pl file. Attackers may leverage this flaw to execute arbitrary scripts in the context of the user's browser. The attack vector is remote, requiring no physical access. The complexity of the attack is low, as it does not require any specialized knowledge or tools.
The attacker requires low privileges to exploit this vulnerability, and user interaction is required; victims need to visit a malicious link. The impact on confidentiality is none, while integrity may be compromised due to the execution of unauthorized scripts.
Risk & Impact Analysis
This vulnerability poses a real-world risk, particularly for organizations utilizing LigeroSmart for ticket management and support systems. If exploited, attackers could gain unauthorized access to sensitive information, potentially leading to further attacks. The blast radius for this vulnerability is limited to users who interact with affected web pages, but the consequences of such an attack can still be significant.
Organizations should address this vulnerability in their priority patch cycle. The low CVSS score indicates that while the risk is not critical, it should not be ignored, especially given the public disclosure of the exploit.
