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 · unedited
ALLNET ALL-RUT22GW v3.3.8 was discovered to store hardcoded credentials in the libicos.so library.

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 confidence

The ALLNET ALL-RUT22GW router firmware v3.3.8 contains hardcoded credentials embedded within the libicos.so compiled library file. These credentials are accessible to anyone who obtains the firmware or can extract the library from the device, potentially granting unauthorized administrative access to the device.

MitigationContact ALLNET for an updated firmware version that removes hardcoded credentials. If no update is available, consider network segmentation and implementing additional authentication controls to limit exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed firmware version
    Access the router's web administration interface or check via CLI/SSH using 'cat /proc/version' or 'fw_printenv' or look for version file in /etc or /var. On the web interface, navigate to System > Administration or Status page to view firmware version.
    Affected if The firmware version is exactly 3.3.8
  2. Locate the libicos.so library file
    Extract firmware filesystem via binwalk or directly access the device via SSH/Telnet and search for 'libicos.so' using 'find / -name libicos.so 2>/dev/null' or check typical library directories like /lib, /usr/lib, /opt/lib.
    Affected if The libicos.so file exists on the device or in extracted firmware
  3. Inspect the binary for hardcoded credentials
    Use strings extraction on the library: 'strings libicos.so | grep -E "(password|passwd|pwd|user|admin)"' or open the binary in a hex editor to search for cleartext credential patterns.
    Affected if Cleartext usernames or passwords are found embedded within the libicos.so binary content

Your environment is affected if the router runs firmware version 3.3.8 and the libicos.so library contains embedded cleartext credentials accessible to attackers.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.
