Introduction: The Hidden Dangers Inside Enterprise Platforms
In an era where cybersecurity threats continue to evolve, a new and alarming discovery has emerged from researchers at Assetnote. Their investigation into ETQ Reliance, a widely used quality management system (QMS), unveiled multiple high-severity vulnerabilities that could grant full SYSTEM-level access to attackers — with zero authentication. This revelation has sent shockwaves through IT security communities, reminding enterprises that even established systems can harbor dangerously overlooked flaws. The heart of this threat lies in simple yet devastating logic errors, particularly in how the application processes usernames and backend authentication logic. As more organizations rely on platforms like ETQ Reliance for compliance, auditing, and automation, the implications of these weaknesses are potentially catastrophic.
Multiple Vulnerabilities Uncovered in ETQ Reliance
ETQ Reliance, known for its centralized document and form management capabilities, has come under scrutiny after cybersecurity researchers at Assetnote exposed a series of critical vulnerabilities in its Java-based architecture. Among these, the most devastating is a flaw identified as CVE-2025-34143, which allows unauthenticated SYSTEM-level access simply by appending a space to the “SYSTEM” username. This oversight completely bypasses authentication checks, due to how MySQL collation treats “SYSTEM” and “SYSTEM ” as equal strings.
Further analysis revealed that once SYSTEM-level access is gained, attackers can execute remote code through custom Jython scripts built into the platform’s form builder, originally intended for report automation. This opens the door to full operating system control, essentially handing the attacker administrative privileges on a silver platter.
The Assetnote team also identified three additional vulnerabilities:
CVE-2025-34141: A reflected XSS issue within the SQLConverterServlet, exploitable without authentication.
CVE-2025-34142: An XML External Entity (XXE) injection in the SSO SAML handler, which can expose sensitive internal files.
A URI parsing logic flaw, allowing authentication bypass using localized text suffixes.
What makes these vulnerabilities especially concerning is the simplicity of exploitation and the depth of access they offer. The combination of poor input validation, reliance on legacy authentication mechanisms, and customizable scripting options created an ideal attack surface for remote code execution (RCE).
The researchers documented how ETQ Reliance’s Java backend fails to properly normalize user input, allowing trivial circumvention of its supposed SYSTEM login protections. When the system checks for exact username equality using Java’s .equals() method, MySQL’s loose collation matching interferes, rendering the security check meaningless. Furthermore, the internal logic grants SYSTEM accounts unrestricted access, including shell command execution, without further authentication checks.
These vulnerabilities have since been reported to Hexagon ETQ, the developers behind Reliance. A patch has been released in NXG 2025.1.2, and administrators are strongly advised to apply it immediately. The ease of exploitation means that both internal and external attackers could breach systems in seconds, with far-reaching consequences. Beyond updating software, organizations must audit all usage logs, especially for suspicious SYSTEM account activity, and thoroughly assess any custom Jython scripts for malicious content.
What Undercode Say: Inside the Exploit Chain and Its Broader Implications
The Fragility of Username Logic
The central issue — a trailing space in the SYSTEM username — may appear insignificant, but its consequences are vast. It’s a prime example of how subtle coding assumptions, such as expecting strict string equality, can be nullified by backend behavior like MySQL’s non-strict collation. Java’s .equals() method does its job, but the database treats "SYSTEM" and "SYSTEM " identically. This leads to a dangerous misalignment between application-layer logic and data-layer behavior, undermining core authentication.
Why Legacy Architecture Still Fails Modern Security Standards
ETQ Reliance’s Java monolith represents an aging architectural model not built with modern security in mind. Despite layering on SSO, scripting, and form-building tools, these additions interact in unpredictable ways. Rather than hardening security, the inclusion of customizable Jython scripting expands the attack surface. This hybrid of old and new creates unintended logic pathways — exactly the kind hackers exploit.
Dangerous Flexibility: When Custom Scripts Become Attack Vectors
The inclusion of Jython scripting, intended to enhance flexibility and automation, inadvertently gives attackers a launchpad for system-wide compromise. With SYSTEM-level privileges, attackers can inject and execute OS commands, pivoting into lateral network movement or data exfiltration. It’s the perfect storm: SYSTEM access, scripting tools, and RCE capabilities all bundled into one exploit chain.
Secure Coding Principles Ignored
A glaring takeaway is the platform’s failure to enforce basic input normalization and strict authentication. It serves as a cautionary tale for all developers: assumptions at the coding stage, such as trusting username strings or database equivalence behavior, must be tested under real-world edge cases. Anything less invites disaster.
The Reality of Enterprise Neglect
Large enterprises often rely on platforms like ETQ Reliance for regulatory compliance, quality assurance, and internal workflows. But because these tools are niche and integrated deeply into internal processes, they often escape thorough external security audits. This creates a blind spot where vulnerabilities can live undetected for years — until researchers or hackers find them.

Assetnote’s Research Highlights Responsible Disclosure Done Right
Despite the severity of their findings, Assetnote followed proper channels, giving Hexagon ETQ time to address the flaws before going public. This underscores the vital role of responsible disclosure in the security ecosystem and highlights the need for vendors to engage proactively with security researchers.
What Needs to Change Moving Forward
Organizations must now prioritize:
Aggressive patch management, especially for critical business apps.
Stringent internal code audits, focusing on input validation and legacy logic.
Limiting or sandboxing scripting capabilities like Jython to reduce RCE risk.
Strengthening logging and alerting on privileged account usage.
The ETQ Reliance incident is a reminder: security isn’t just about firewalls and antivirus — it’s about code, context, and constant vigilance.
🔍 Fact Checker Results
✅ SYSTEM login bypass confirmed via username space flaw (CVE-2025-34143)
✅ Remote code execution achievable using Jython scripting after SYSTEM access
✅ Official patch (NXG 2025.1.2) released by Hexagon ETQ to fix all known flaws
📊 Prediction
⚠️ Expect broader exploitation attempts of ETQ Reliance in the wild over the next few months, especially in unpatched systems.
🔐 Vendors offering scripting and custom logic tools will face increased scrutiny, pushing a trend toward more restrictive, sandboxed implementations.
💼 Enterprise platforms like ETQ will likely undergo more frequent third-party audits and internal red-team testing to avoid similar exposures in future.
