CVE-2025-27261
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedEricsson Indoor Connect 8855 contains an SQL injection vulnerability which if exploited can result in unauthorized disclosure or modification of data.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceEricsson Indoor Connect 8855 contains an SQL injection vulnerability that allows attackers to inject malicious SQL statements through input fields or parameters, potentially enabling unauthorized disclosure or modification of the underlying database contents.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check firmware version on Ericsson Indoor Connect 8855Access the device admin interface or check system settings to view the installed firmware version. Typically found under 'System' or 'About' menu in the web GUI, or via CLI command like 'show version' or 'get firmware-version' if available.Affected if The installed firmware version is earlier than 2025.q2 (e.g., 2024.q4, 2024.q3, etc.)
-
Verify network accessibility of the device management interfaceDetermine if the device web interface or administrative ports are reachable from untrusted networks. Check firewall rules, VLAN configuration, or perform a port scan (e.g., nmap) against the device IP on common ports (80, 443, 8080).Affected if The administrative interface is exposed to untrusted networks or the internet without proper access controls.
-
Review device logs for SQL injection indicatorsAccess system logs through the admin interface or log files. Look for unusual database error messages, unexpected SQL syntax in log entries, or repeated failed authentication attempts with query-like patterns.Affected if Logs contain SQL error messages (e.g., 'SQL syntax', 'MySQL syntax error', database connection failures) or suspicious query patterns.
-
Check for unauthorized data access or modificationReview database-backed data accessible through the device interface for unexpected changes, new user accounts, or data exfiltration indicators. Audit any API or reporting features that interact with the backend database.Affected if Unexpected records, unauthorized administrative accounts, or data anomalies exist that could indicate successful SQL injection exploitation.
You are affected if your Ericsson Indoor Connect 8855 runs firmware versions prior to 2025.q2 and the device management interface is network-accessible to potential attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2025.q2
Apply vendor-provided firmware patches when available; until then, restrict network access to the device management interface and monitor for suspicious SQL-like patterns in requests.
2025.q2 (or any subsequent release)
- 1. Identify the current firmware version of the Ericsson Indoor Connect 8855 device
- 2. Download the firmware version 2025.q2 or later from an official Ericsson source
- 3. Review the firmware upgrade instructions in the Ericsson product documentation
- 4. Perform a backup of the current configuration if supported
- 5. Apply the firmware upgrade following the vendor's documented procedure
- 6. Verify the device is functioning normally after upgrade
- 7. Confirm the firmware version has been updated to 2025.q2 or later
