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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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), 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 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 official patches, European organizations should implement immediate compensating controls. First, apply strict input validation and output encoding on all user-supplied data, especially the 'Message' parameter in the /home.jsp endpoint, to neutralize malicious scripts. If source code modification is not feasible, deploy a web application firewall (WAF) with custom rules to detect and block XSS payloads targeting this parameter. Conduct regular security audits and penetration tests focusing on this endpoint. Educate users to recognize suspicious URLs and avoid clicking untrusted links. Monitor web server logs and user activity for signs of attempted exploitation. Consider isolating or restricting access to the vulnerable ERP portal until a vendor patch is available. Finally, maintain up-to-date backups and incident response plans to quickly recover from potential attacks.

Description

A security vulnerability has been detected in Advaya Softech GEMS ERP Portal up to 2.1. This affects an unknown part of the file /home.jsp?isError=true of the component Error Message Handler. The manipulation of the argument Message leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Advaya Softech GEMS ERP Portal, this vulnerability poses a risk of client-side attacks that can compromise user sessions, steal sensitive information, or manipulate displayed content. Since ERP portals often contain critical business data and user credentials, successful exploitation could lead to unauthorized access to internal systems or data leakage. The lack of vendor response and patches increases exposure time, potentially allowing attackers to craft targeted phishing campaigns or deploy persistent malicious scripts. The impact on confidentiality is limited but non-negligible, while integrity risks are more pronounced due to script injection capabilities. Availability is not directly affected. Organizations relying heavily on this ERP system for business operations may face reputational damage and operational disruptions if attackers leverage this vulnerability to deface portals or conduct social engineering attacks.

Summary

CVE-2025-15170 is a cross-site scripting vulnerability identified in Advaya Softech's GEMS ERP Portal, affecting versions 2.0 and 2.1. The vulnerability resides in the error message handler component, specifically in the /home.jsp?isError=true endpoint, where the 'Message' parameter is not properly sanitized or encoded before being reflected in the response. This improper handling allows an attacker to inject arbitrary JavaScript code that executes in the context of the victim's browser when they visit the crafted URL. The attack vector is remote and does not require any authentication or privileges, but it does require user interaction to trigger the malicious script. The CVSS 4.0 score is 5.3 (medium severity), reflecting the ease of exploitation (network accessible, no privileges required) but limited impact on confidentiality and availability, with primarily integrity affected through script injection. The vulnerability could be exploited for session hijacking, phishing, or defacement attacks. The vendor was notified early but has not issued any patches or advisories, and no known exploits have been observed in the wild yet. The public disclosure of the exploit increases the risk of opportunistic attacks against unpatched systems.
