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
The optional "LDAP contacts provider" could be abused by privileged users to inject LDAP filter strings that allow to access content outside of the intended hierarchy. Unauthorized users could break confidentiality of information in the directory and potentially cause high load on the directory server, leading to denial of service. Encoding has been added for user-provided fragments that are used when constructing the LDAP query. No publicly available exploits are known.

Upgrade available Upgrade to 7.10.6 or later
Fixed in 7.10.6
Recommended fix Moderate confidence

Ox App Suite version 7.10.7 or later, or version 8.17 or later (any version after the affected releases)

  1. Identify the current installed version of Ox App Suite using the admin dashboard or command-line tools
  2. Determine if the LDAP contacts provider feature is enabled in your installation
  3. If enabled, upgrade to a version higher than 7.10.6 (such as 7.10.7 or later) or version higher than 8.16 (such as 8.17 or later)
  4. After upgrading, verify that the LDAP contacts provider still functions correctly with proper encoding applied to user-provided LDAP filter fragments
  5. Test that the LDAP query construction now properly sanitizes user input to prevent LDAP injection
