CVE-2026-25200 & CVE-2026-25202 Critical CVEs Alert: MagicINFO 9 Server at Risk
February 2, 2026
On February 2, 2026, two critical CVEs were assigned to Samsung MagicINFO 9 Server, each with a CVSS score of 9.8 (Critical). These vulnerabilities present a serious risk to organizations running affected versions, particularly because MagicINFO servers are often deployed in enterprise networks with elevated privileges and broad internal access.
Although no public exploits are currently known, the combination of high impact, low attack complexity, and enterprise relevance makes these CVEs likely candidates for future exploitation.
This article explains the vulnerabilities, their potential impact, and clear recommendations for defenders.
CVE-2026-25200 — MagicINFO 9 Server Unrestricted File Upload
- Severity: Critical (CVSS 9.8)
- Disclosure Date: February 2, 2026
- Affected Product: Samsung MagicINFO 9 Server
Description
CVE-2026-25200 is an unrestricted file upload vulnerability in MagicINFO 9 Server. The application fails to properly validate uploaded content, allowing unauthenticated attackers to upload HTML files.
Once uploaded, these files can be rendered by the application, enabling stored cross-site scripting (XSS) attacks.
Impact
If exploited, this vulnerability may allow attackers to:
- Execute malicious scripts in users’ browsers
- Hijack active user sessions
- Steal credentials or authentication tokens
- Perform unauthorized administrative actions
- Gain persistent access to MagicINFO management functions
Because MagicINFO is often managed by privileged users, a single successful XSS payload can lead to full administrative compromise.
Exploit Status
At the time of disclosure, no public proof-of-concept or active exploitation has been reported. However, the vulnerability is considered easy to trigger, and similar flaws have historically been weaponized quickly after disclosure.
Remediation and Mitigation
- Monitor Samsung security advisories for official patches
- Upgrade to MagicINFO version 21.1090.1 or later once available
- Restrict access to upload functionality using network segmentation
- Deploy a Web Application Firewall (WAF) with rules for file upload abuse and XSS
- Monitor logs for suspicious upload activity or unexpected HTML content
CVE-2026-25202 — MagicINFO 9 Server Hardcoded Credentials
- Severity: Critical (CVSS 9.8)
- Disclosure Date: February 2, 2026
- Affected Product: Samsung MagicINFO 9 Server
Description
CVE-2026-25202 is caused by hardcoded database credentials embedded within MagicINFO 9 Server. These credentials allow network-accessible attackers to authenticate directly to the backend database.
This flaw bypasses normal authentication controls and does not require user interaction.
Impact
Successful exploitation may allow attackers to:
- Read, modify, or delete database contents
- Create or modify administrative accounts
- Deploy malware or backdoors through database manipulation
- Achieve full system compromise
- Move laterally within the enterprise network
Because database access often equates to complete application control, this vulnerability represents a critical breach point.
Exploit Status
The vulnerability is newly disclosed, and no public exploit code has been observed yet. However, hardcoded credential vulnerabilities are highly attractive to attackers due to their reliability and low exploitation complexity.
Recommendations for Defenders
Organizations running MagicINFO 9 Server should act immediately:
Immediate Actions
- Identify all MagicINFO 9 Server instances across the environment
- Limit network access to MagicINFO servers using firewalls or ACLs
- Monitor database access logs for unknown or anomalous connections
- Assume potential exposure and review logs retrospectively
Patching and Hardening
- Apply vendor patches as soon as they are released
- Remove or rotate any embedded or default credentials if possible
- Enforce strong database authentication and network isolation
- Run MagicINFO services with the least privileges required
Detection and Monitoring
- Implement continuous monitoring for file upload abuse
- Alert on unexpected HTML or script content within application directories
- Watch for suspicious administrative actions or account creation
- Add MagicINFO-specific indicators to SIEM detection rules
Final Thoughts
CVE-2026-25200 and CVE-2026-25202 represent high-risk, enterprise-impacting vulnerabilities. Even without active exploitation, their characteristics suggest they will quickly attract attacker attention.
Security teams should treat these CVEs as urgent remediation priorities, track vendor guidance closely, and apply compensating controls until patches are fully deployed.
Staying ahead of exploitation starts with acting early before these CVEs move from disclosure to weaponization.
