CVE-2026-1062: Low Vulnerability in xiweicheng teamwork management system

A flaw has been found in xiweicheng TMS up to version 2.28.0. This vulnerability allows server-side request forgery (SSRF) through the manipulation of the argument url in the function Summary of the file src/main/java/com/lhjz/portal/util/HtmlUtil.java. Attackers may leverage this flaw to initiate attacks remotely, potentially leading to unauthorized access to internal resources.

The CVSS score for this vulnerability is 2.1, categorized as low severity. While it may not pose an immediate critical risk, organizations should still be aware of its potential impacts, especially in environments where sensitive internal systems could be accessed through SSRF attacks. The exploit has been published and may be used, thus organizations should prioritize addressing this vulnerability.

Organizations should address this vulnerability in their priority patch cycle to mitigate possible exploitation. Regular vulnerability assessments and timely patching are vital components of a robust security posture.

The importance of maintaining up-to-date software cannot be overstated, particularly in the face of known vulnerabilities. By keeping systems patched, organizations can reduce their exposure to potential attacks and enhance their overall security.

Vulnerability Details

A flaw has been found in xiweicheng TMS up to version 2.28.0. This affects the function Summary of the file src/main/java/com/lhjz/portal/util/HtmlUtil.java. This manipulation of the argument url causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been published and may be used.

Technical Analysis

The root cause of this vulnerability lies in improper validation of user input. Specifically, the application allows manipulation of the URL parameter, which can be exploited to redirect requests to unintended destinations. This vulnerability can be exploited over the network without requiring user interaction.

The attack vector is classified as network-based, with low attack complexity. It requires low privileges to exploit, meaning an attacker with basic access can initiate the attack. There is no user interaction required for this type of exploitation. The impacts on confidentiality, integrity, and availability are all low, as indicated by the CVSS metrics.

Risk & Impact Analysis

Risk to organizations includes potential unauthorized access to internal systems through SSRF attacks. While the severity is low, the blast radius can be significant if sensitive internal services are exposed. Organizations should assess their deployment of xiweicheng TMS and consider the implications of this vulnerability.

Given the CVSS score, the urgency for patching this vulnerability can be categorized as moderate. Organizations should schedule remediation and incorporate this into their vulnerability management program.

Exploitation Status

Affected Versions

The affected versions of xiweicheng TMS are all versions prior to vendor patch 2.28.0. Organizations should ensure they are running the patched version to mitigate this vulnerability.

Mitigation & Remediation

Organizations should prioritize patching immediately. It is crucial to upgrade to the latest version of xiweicheng TMS to close this vulnerability. In the absence of a patch, organizations could implement network controls to restrict access to sensitive internal resources that could be targeted through SSRF.

Additionally, organizations should consider regular security assessments and penetration testing to identify and remediate similar vulnerabilities. For comprehensive security evaluation, organizations may explore penetration testing services.

Detection Guidance

Monitoring logs for unusual request patterns can help detect potential SSRF attempts. Look for indicators such as requests that target internal services or unexpected URL manipulations. Behavioral anomalies in web application interactions should also be investigated to identify potential exploitation of this vulnerability.

AppSecure Threat Intelligence Insight

The long-term significance of this vulnerability lies in its representation of a common flaw in web applications: improper input validation leading to SSRF. Security teams should recognize this pattern and incorporate preventive measures in their development practices.

This vulnerability highlights the necessity for continuous threat modeling and the importance of robust security testing in development cycles. For more insights, you may refer to the vulnerability management program and the penetration testing methodology articles for best practices.

In conclusion, addressing this vulnerability should be part of a broader strategy to enhance application security and protect against evolving threats.
