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
Sharp Zaurus PDA SL-5000D and SL-5500 uses a salt of "A0" to encrypt the screen-locking password as stored in the Security.conf file, which makes it easier for local users to guess the password via brute force methods.

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

Sharp Zaurus PDA models SL-5000D and SL-5500 use a hardcoded salt value of 'A0' when encrypting screen-locking passwords stored in the Security.conf file. This static salt significantly reduces the computational work required for brute-force password attacks, as attackers can precompute hash tables using this known salt.

MitigationReplace the static salt with a cryptographically random per-device or per-installation salt, and use a modern password hashing function like bcrypt, scrypt, or Argon2. If the device firmware cannot be updated, consider alternative physical security measures to protect the Security.conf file.

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 device model
    Check if the device is a Sharp Zaurus SL-5000D or SL-5500 model. This can be done by checking the device label, system information, or boot screen during startup.
    Affected if The device is a Sharp Zaurus SL-5000D or SL-5500 model.
  2. Locate the Security.conf file
    Access the device's file system and locate the Security.conf file. On the Zaurus, this is typically found in the /home/etc/ directory or the device's configuration directory where security settings are stored.
    Affected if The Security.conf file exists on the device.
  3. Examine the Security.conf file for password hash entries
    Open the Security.conf file using a text editor or cat command and look for entries related to screen lock password or encrypted password fields. Look for patterns indicating stored password hashes.
    Affected if The Security.conf file contains encrypted password or hash entries for the screen lock.
  4. Inspect the salt value used in password encryption
    Examine the password hash entries in Security.conf for the salt component. Look for the hexadecimal value 'A0' appearing consistently as the salt prefix or component in the password hash string.
    Affected if The salt value in the password hash entry is 'A0', indicating the hardcoded static salt is in use.

The device is affected if it is a Sharp Zaurus SL-5000D or SL-5500 with a Security.conf file containing screen lock password hashes that use the hardcoded salt value 'A0'.

Mitigation

Replace the static salt with a cryptographically random per-device or per-installation salt, and use a modern password hashing function like bcrypt, scrypt, or Argon2. If the device firmware cannot be updated, consider alternative physical security measures to protect the Security.conf file.
