Network-reachable authorization bypass needing no auth or interaction yields PR:N/UI:N/AC:L, and code execution crossing the component boundary justifies S:C with full C/I/A impact.

AnalysisAI
Remote code execution in Adobe Campaign Classic (ACC) version 7.4.3 build 9396 and earlier allows unauthenticated attackers to bypass authorization controls and run arbitrary code in the context of the current user. The flaw stems from an incorrect authorization check (CWE-863) reachable over the network with no user interaction, and the changed scope means impact can extend beyond the vulnerable component. It carries a maximum CVSS 10.0 rating; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Technical ContextAI
Adobe Campaign Classic is an on-premises/hybrid marketing automation and cross-channel campaign management platform that exposes web-facing application server endpoints and a SOAP/HTTP API. The vulnerability is classified as CWE-863 (Incorrect Authorization), meaning an authorization decision is performed but uses a flawed check, allowing an action to proceed when it should be denied. Per the CPE (cpe:2.3:a:adobe:adobe_campaign_classic_(acc):*) this affects the Adobe Campaign Classic application across versions up to and including 7.4.3 build 9396. Combined with the 'arbitrary code execution' outcome and a changed CVSS scope (S:C), the broken authorization likely permits an attacker to reach privileged server-side functionality that can execute code, with consequences crossing the original security boundary (e.g., from the application layer into the underlying host or adjacent components).
RemediationAI
Patch available per vendor advisory: upgrade Adobe Campaign Classic to the fixed release identified in Adobe Security Bulletin APSB26-69 (https://helpx.adobe.com/security/products/campaign/apsb26-69.html), as builds at or below 7.4.3 build 9396 are vulnerable; the exact patched build should be confirmed directly from that bulletin before deployment as a specific fix version was not included in the provided data. Until the upgrade is applied, reduce exposure by restricting network access to the Adobe Campaign application and API endpoints - place the server behind a VPN or IP allowlist and block direct internet access to the management/SOAP interfaces, accepting that this may disrupt remote operators or integrated external channels that legitimately call those endpoints. Monitor application and web-server logs for anomalous authorization-bypass patterns and unexpected code-execution or process-spawn activity from the ACC service account as a detective control while patching is scheduled.
