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
UBB.threads is vulnerable to Blind SQL Injection, allowing attackers with access to the Members in Control Panel to interact with the underlying database. Due to insufficient input sanitization, an attacker can extract sensitive information, such as user credentials, by manipulating SQL queries through time-based or boolean-based techniques. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.

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

UBB.threads 7.7.5 contains a Blind SQL Injection vulnerability in the Members section of the Control Panel. Attackers with Control Panel access can exploit insufficient input sanitization to manipulate SQL queries through time-based or boolean-based techniques, enabling extraction of sensitive data such as user credentials.

MitigationImplement parameterized queries (prepared statements) for all database operations in the Members CP functionality and add comprehensive input validation/sanitization for all user-supplied parameters.

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. Confirm UBB.threads installation and version
    Locate the UBB.threads installation directory and check for version indicators such as a version file, footer text, or admin panel version display. Check files like version.php, or inspect the HTML footer/source of any UBB.threads page for version strings.
    Affected if The installed version is 7.7.5 or falls within an unpatched version range for this release.
  2. Identify Control Panel access
    Determine if the UBB.threads Control Panel is accessible. Look for the /controlpanel/ or /cp/ directory path in the web root, or check if admin/moderator accounts exist in the users table that can access the Control Panel.
    Affected if Control Panel access exists for any user account, making the vulnerable Members section reachable.
  3. Locate Members section functionality
    Identify the Members section within the Control Panel. This is typically accessed via a Members or User Management link in the Control Panel navigation. Check for scripts handling member listing, member search, or member profile operations.
    Affected if The Members CP functionality is present and accessible to the attacker.
  4. Inspect input handling in Members CP
    Examine the code handling user-supplied parameters in the Members section (such as member IDs, search queries, or sort parameters). Look for direct use of $_POST or $_GET variables in SQL queries without parameterized queries or proper sanitization.
    Affected if User-supplied parameters from the Members section are used directly in SQL queries without prepared statements or input validation.

A user is affected if they run UBB.7.7.5 with an accessible Control Panel where the Members section processes user input directly in SQL queries.
