xiweicheng TMS <= 2.28.0 HtmlUtil.java Server-Side Request Forgery (SSRF) Vulnerability (CVE-2026-1062)
Executive & SecOps Summary
SECOPS ASSESSMENTxiweicheng TMS up to version 2.28.0
Unauthenticated remote attackers can access internal network resources, invoke internal APIs, or potentially escalate to Remote Code Execution (RCE)
Apply the latest security patches, sanitize the 'url' parameter in HtmlUtil.java, or deploy WAF rules to block outbound requests to private IP ranges
Affected Products & Version Scope
Remediation & Live Workaround Commands
PATCH & WORKAROUND1. Official Patch & Version Upgrade Commands
Upgrade your xiweicheng TMS installation to the latest patched version. If you are managing the project via Maven, update the dependency version in your pom.xml and rebuild the application:
# Clean and rebuild the Maven project after updating the dependency version
mvn clean package -DskipTests2. Temporary Workaround & Hardening Configuration
If an immediate upgrade is not feasible, implement input validation in your reverse proxy or Web Application Firewall (WAF) to block requests containing private IP addresses in the query parameters.
# Nginx configuration snippet to block potential SSRF payloads
if ($query_string ~* "url=.*(127\.0\.0\.1|localhost|169\.254\.|10\.|172\.(1[6-9]|2[0-9]|3[0-1])\.|192\.168\.)") {
return 403 'Access Denied: SSRF Attempt Detected';
}3. Log Audit & IoC Verification Commands
Scan your application access logs to identify suspicious requests targeting internal IP addresses or loopback interfaces via the url parameter.
# Search for suspicious internal IP patterns in the application access logs
grep -Ei 'url=.*(127\.0\.0\.1|localhost|169\.254|192\.168|10\.)' /var/log/tms/access.logBlock Exploits Instantly with Managed Virtual Patching Rules
Can't patch production immediately? Deploy managed WAF rules at the edge to intercept RCE, SQLi, and deserialization payloads before they hit your origin server.
Technical Root Cause & Exploitation Mechanics
1. Vulnerability Overview & Root Cause
A critical Server-Side Request Forgery (SSRF) vulnerability (CVE-2026-1062) has been identified in the Summary function of the src/main/java/com/lhjz/portal/util/HtmlUtil.java file in xiweicheng TMS. The application fails to properly validate and sanitize the user-supplied url argument before initiating a server-side HTTP request, allowing arbitrary destination targeting.
2. Exploitation Mechanics & Attack Scenario
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted request containing internal IP addresses (e.g., 127.0.0.1, 10.0.0.0/8, 192.168.0.0/16) or cloud metadata endpoints (e.g., 169.254.169.254) in the url parameter. Since the request originates from the trusted application server, it bypasses perimeter firewalls to access internal services, databases, or sensitive metadata. Public exploits are currently available, increasing the likelihood of active exploitation.
3. Infrastructure & Business Impact
With a CVSS score of 9.8 (Critical), this vulnerability poses a severe threat to enterprise infrastructure. Successful exploitation can lead to unauthorized access to internal administrative panels, exposure of sensitive configuration data, credential theft from cloud metadata services, and potential lateral movement within the internal network.
Official Vendor Advisories & References
A flaw has been found in xiweicheng TMS up to 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.
