Summary

CVE-2026-51077 is an SQL injection vulnerability (CWE-89) in DedeCMS version 5.7.118. A remote attacker can inject arbitrary SQL through the sqlquery parameter of the sys_sql_query.php component, allowing extraction of sensitive information from the backing database. The issue carries a CVSS v3.1 base score of 7.5 (HIGH) with a network attack vector.

Technical details

  • Root cause: Insufficient input neutralization in the sys_sql_query.php SQL command-line tool. Per the public proof-of-concept, the safeCheck variable in /dede/config.php is set to FALSE, which disables the security validation that would otherwise be enforced before queries are executed.
  • Trigger conditions: A crafted SQL payload is supplied via the sqlquery parameter to the sys_sql_query.php component (exposed through the backend "System → SQL Command Line Tool"). Because filtering is bypassed, the statement is passed to the database driver and executed.
  • Attack vector: Network (remote). The published PoC demonstrates error-based extraction (e.g., extractvalue()), which leaks database contents through returned error messages.
  • Impact: Disclosure of sensitive information from the database (high confidentiality impact). No integrity or availability impact is reflected in the published CVSS vector.

Affected software

  • DedeCMS v5.7.118

Severity

  • CVSS v3.1 Base Score: 7.5 (HIGH)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: No fixed release has been confirmed for this CVE at the time of writing. Monitor the official DedeCMS site (https://www.dedecms.com/) for a patched version and apply it as soon as it is published.
  • If no patch is available:
    • Restrict network access to the administrative backend (the /dede/ directory and the sys_sql_query.php SQL command-line tool), for example via IP allow-listing or authentication at the web-server/WAF layer.
    • Ensure the safeCheck security check in /dede/config.php is not disabled.
    • Disable or remove the SQL command-line tool if it is not required for operations.
    • Monitor web and database logs for anomalous sqlquery requests and error-based injection patterns.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
