StudIP SQL Injection Vulnerability Allows Code Execution and Information Disclosure

CVE advisorySeverity: CRITICAL (CVSS 9.1)

CVE-2026-51346

Stud.IP is a web-based learning management system designed to be accessed over a network by many users. Because it serves as a web application platform, it is typically deployed as an internet-facing or campus-wide web service, making it likely to be reachable from an external network.

Horizon Alert

Summary of the vulnerability and why it matters

A SQL injection vulnerability has been identified in StudIP software, potentially allowing unauthorized remote access to execute code and access sensitive information.

  • Database injection in learning system.
  • Could expose sensitive information.
  • Confirm relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending a specially crafted request to a StudIP web server over the network. This request would target the `store()` functions, which are susceptible to SQL injection. If successful, the attacker could execute arbitrary code and access sensitive information on the server.

  • Attacker accesses the system over the network.
  • Vulnerable `store()` functions are triggered.
  • Arbitrary code execution and information disclosure.

Live Threat

Current exploitation, exposure, and threat context

A remote attacker could exploit a SQL injection vulnerability in StudIP's `store()` functions to execute arbitrary code and access sensitive information. This could occur when the application is exposed to the network and the vulnerable functions are called.

  • Sensitive information in StudIP.
  • Exploitation via network calls to `store()`.
  • Unauthorized access and code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

This SQL injection vulnerability in StudIP affects learning management systems, typically managed by application owners and infrastructure teams. The first practical step is to identify all StudIP instances, determine their reachability and criticality, and pinpoint the accountable owner for each. This will allow for a risk-based remediation plan, potentially involving coordination with the StudIP vendor.

  • Application owners should investigate StudIP instances.
  • Verify external reachability and business criticality.
  • Plan remediation based on identified risk.

Frequently asked questions

What is StudIP and how is it used?

StudIP is a web-based learning management system (LMS). Educational institutions and organizations use it to host course materials, manage student communication, and track academic progress through a centralized web interface.

What does SQL injection mean for CVE-2026-51346?

This vulnerability is classified as CWE-89, or improper neutralization of special elements used in an SQL command. In plain terms, the application fails to properly filter user input before sending it to the database, allowing an attacker to manipulate backend queries to run unauthorized code or view data.

How does an attacker trigger this vulnerability?

An attacker initiates the vulnerability by sending a maliciously crafted network request that targets the application's store() functions. Simply navigating the site normally or performing standard user tasks does not trigger the bug; the request must specifically interact with these vulnerable processing functions.

Is my StudIP instance at risk?

According to Halo Surface Signal, StudIP is typically deployed as a campus-wide or internet-facing service, meaning it is often reachable from external networks. If your instance is accessible via the internet, it is more likely to be reachable by an external attacker compared to a system restricted to a private internal network.

Do I need to update my software immediately?

You should begin by identifying all running instances of StudIP and determining their network reachability. Once you have an inventory, coordinate with your infrastructure team to verify your version and prepare to apply the vendor-supplied updates that address these vulnerable functions.
