Summary

CVE-2023-29050 is a high-severity LDAP Injection (CWE-90) vulnerability in Open-Xchange Ox App Suite. Its CVSS base score is 7.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 24% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover LDAP injection flaws through static analysis or crafted test cases.

Input validation directly stops untrusted data from reaching an LDAP query builder without neutralization of special characters.

Secure engineering principles require safe query construction and escaping that structurally prevents LDAP injection.

A.8.15 Logging partial match
finds

Logging supports detection of injection attempts but does not prevent the weakness.

finds

Monitoring activities can identify active injection attacks after they occur.

blocks

A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reach LDAP injection as one injection-class defect, but leaves a bounded remainder (e.g. incomplete implementation of those practices, outsourced development without full assurance, or non-code injection vectors)

blocks

Application security requirements include explicit rules for safe construction of directory queries, mitigating LDAP injection.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
