Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
VMware Carbon Black App Control versions 8.7.x prior to 8.7.8, 8.8.x prior to 8.8.6, and 8.9.x prior to 8.9.4 contain an injection vulnerability tracked as CVE-2023-20858 and assigned CWE-74. The flaw resides in the product’s administration console and carries a CVSS 3.1 base score of 7.2 reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability when successfully exploited.
A malicious actor who already possesses privileged administrative access to the App Control console can supply specially crafted input that results in command or code injection, ultimately granting access to the underlying server operating system and full control over the host.
The official VMware advisory VMSA-2023-0004 recommends upgrading affected installations to the fixed releases listed above to eliminate the injection vector. The associated EPSS score rose from a low baseline to a peak of 0.0641 on 2026-03-03 before receding to its current value of 0.0111, indicating a period of increased exploitation interest after public disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.
Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.

Security testing in development catches injection vulnerabilities before release.
Logging supports detection of injection attempts but does not prevent the weakness.
Monitoring activities can identify active injection attacks after they occur.
Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.
Application security requirements explicitly call for controls against injection attacks in software design.
Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.
