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
Dell EMC AppSync, versions from 4.2.0.0 to 4.6.0.0 including all Service Pack releases, contain an exposure of sensitive information vulnerability in AppSync server logs. A high privileged remote attacker could potentially exploit this vulnerability, leading to the disclosure of certain user credentials. The attacker may be able to use the exposed credentials to access the vulnerable system with privileges of the compromised account.

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 · high confidence

Dell EMC AppSync versions 4.2.0.0 through 4.6.0.0 write sensitive user credentials to server logs. A high-privileged remote attacker with access to the logs can extract these credentials and gain unauthorized access to the system using the compromised account privileges.

MitigationConfigure log filtering to exclude sensitive credential data from logs, and rotate any credentials that may have been exposed through the logs. Restrict access to server logs to minimize 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 Dell EMC AppSync version
    Access the AppSync administration console or use the product's built-in version command. Common locations include the About section in the UI or running 'esrs_management -v' or similar product-specific commands. Consult Dell documentation for your exact version retrieval method.
    Affected if The installed version is 4.2.0.0 through 4.6.0.0 (specifically below 4.6.0.2)
  2. Locate AppSync server log files
    Navigate to the default log directory for AppSync, typically found under /var/log/ or within the product installation directory. Common log file names include appsync.log, server.log, or audit.log. Check Dell EMC AppSync documentation for your specific log paths.
    Affected if Log files exist and are accessible on the system
  3. Search logs for sensitive credential patterns
    Use grep or similar text search tools to scan log files for patterns indicating credential exposure. Look for strings containing 'password', 'PASSWORD', 'credential', 'secret', 'api_key', or base64-encoded strings that may represent credentials. Search for patterns like 'password=***' or authentication tokens.
    Affected if Log files contain plaintext or encoded credential data such as passwords, API keys, or authentication tokens
  4. Verify log file access permissions
    Check file system permissions on the identified log files using 'ls -la' command. Determine which users and groups have read access to the logs. Review whether untrusted users or the 'others' group have any read permissions.
    Affected if Log files are readable by untrusted users or groups beyond authorized administrators

You are affected if your AppSync version is 4.2.0.0 through 4.6.0.0 and log files contain exposed credentials or are accessible to unauthorized users.

Upgrade available Upgrade to 4.6.0.2 or later
Fixed in 4.6.0.2
Interim mitigation

Configure log filtering to exclude sensitive credential data from logs, and rotate any credentials that may have been exposed through the logs. Restrict access to server logs to minimize exposure.

Recommended fix Moderate confidence

Upgrade to Dell EMC AppSync version 4.6.0.2 or later

  1. 1. Obtain the Dell EMC AppSync version 4.6.0.2 or later update from Dell support portal at www.dell.com
  2. 2. Review the release notes and upgrade documentation for version 4.6.0.2
  3. 3. Create a full backup of the current AppSync configuration and database
  4. 4. Stop all AppSync services before applying the update
  5. 5. Apply the version 4.6.0.2 upgrade following Dell's documented upgrade procedure
  6. 6. Verify the upgrade was successful by checking the AppSync version
  7. 7. Review new log files to confirm sensitive information is no longer being written
Caveat Review Dell upgrade documentation for any configuration or compatibility changes between your current version and 4.6.0.2
