CVE-2021-43782
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 · uneditedTuleap is a Libre and Open Source tool for end to end traceability of application and system developments. This is a follow up to GHSA-887w-pv2r-x8pm/CVE-2021-41276, the initial fix was incomplete. Tuleap does not sanitize properly the search filter built from the ldap_id attribute of a user during the daily synchronization. A malicious user could force accounts to be suspended or take over another account by forcing the update of the ldap_uid attribute. Note that the malicious user either need to have site administrator capability on the Tuleap instance or be an LDAP operator with the capability to create/modify account. The Tuleap instance needs to have the LDAP plugin activated and enabled for this issue to be exploitable. The following versions contain the fix: Tuleap Community Edition 13.2.99.83, Tuleap Enterprise Edition 13.1-6, and Tuleap Enterprise Edition 13.2-4.
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 analysisUntrusted input crosses into a downstream interpreter — SQL, a shell, an HTML page, an LDAP query — without being kept separate from the commands around it, so the attacker's data is read as instructions. This is the parent class behind SQL injection, cross-site scripting, and command injection alike. The durable fix is the same everywhere: keep data and code apart at every boundary, using parameterisation or context-aware encoding rather than building interpreted strings by concatenation.

Tuleap Community Edition 13.2.99.83, Tuleap Enterprise Edition 13.1-6, or Tuleap Enterprise Edition 13.2-4 (depending on your edition and major version)
- 1. Identify the currently installed Tuleap version by checking the About page or the version file
- 2. Verify if the LDAP plugin is activated and enabled on the instance
- 3. If using Tuleap Community Edition, upgrade to version 13.2.99.83 or later
- 4. If using Tuleap Enterprise Edition 13.1.x, upgrade to version 13.1-6 or later
- 5. If using Tuleap Enterprise Edition 13.2.x, upgrade to version 13.2-4 or later
- 6. After upgrade, verify the LDAP plugin continues to function correctly
- 7. Review LDAP user synchronization logs to confirm the fix is applied
