CVE-2023-22232
Published: 17 February 2023
Summary
CVE-2023-22232 is a medium-severity Improper Access Control (CWE-284) vulnerability in Adobe Connect. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Adobe Connect versions 11.4.5 and earlier as well as 12.1.5 and earlier are affected by an Improper Access Control vulnerability that results in a security feature bypass. The flaw carries a CVSS 3.1 score of 5.3 and is tracked under CWE-284. Exploitation requires no user interaction and can be performed over the network without authentication, allowing an attacker to affect the integrity of a minor feature.
An unauthenticated remote attacker can leverage the weakness to bypass intended access controls and alter limited integrity properties within the application. Because the attack does not depend on user interaction or credentials, it can be launched directly against exposed Adobe Connect instances.
The official Adobe security bulletin APSB23-05, available at helpx.adobe.com/security/products/connect/apsb23-05.html, addresses the issue and supplies remediation guidance for affected Connect releases. Public exploit references, including a local file disclosure report on Packet Storm, align with the same advisory.
The associated EPSS score has remained elevated, reaching a peak of 0.8847 and currently sitting at 0.8427.

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.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
