Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability has been identified in Stimulsoft reporting products that could allow unauthorized remote code execution. The issue arises from how the software handles local file system access, potentially enabling an attacker to craft reports that read or write to local directories and files, or embed malicious code within report elements.
- Unrestricted file access allows remote code execution.
- Critical flaws in reporting tools require attention.
- Confirm product relevance and potential exposure.
Attack Path
How an attacker could exploit the issue
An attacker can craft a report containing malicious source code that allows them to read or write to the local file system. This report, when rendered, enables the attacker to execute arbitrary code, potentially leading to complete system compromise.
- No authentication required.
- Render a crafted report.
- Remote code execution possible.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an attacker to execute arbitrary code by including source code that interacts with the local file system to read or write files. It may also enable an attacker to craft a report containing a variable that holds collected data, which is then rendered in the report.
- System files and directories could be affected.
- Malicious source code can be included.
- Unauthorized file access and data manipulation.
Operational Fix
Recommended remediation, mitigation, and detection steps
Application owners responsible for Stimulsoft Designer and Viewer components should lead the response to this critical remote code execution vulnerability. The initial step involves identifying all instances of the affected Stimulsoft products across your environment, confirming their accessibility from the internet, and assessing their business criticality. Once ownership and risk are clarified, a remediation plan can be developed, potentially involving vendor coordination or temporary risk reduction measures.
- Confirm application owner and asset criticality.
- Verify external reachability and exposure.
- Plan remediation or temporary risk reduction.
