Adobe Campaign Classic (ACC) versions 7.4.3 build 9394 and earlier are affected by a Server-Side Request Forgery (SSRF) vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.

AnalysisAI
Server-side request forgery in Adobe Campaign Classic (ACC) versions 7.4.3 build 9394 and earlier escalates to arbitrary code execution in the context of the current user, with a maximum CVSS 10.0 reflecting unauthenticated network exploitation and scope change. No public exploit identified at time of analysis, but the vendor advisory APSB26-66 confirms the flaw and the trivial attack complexity (AC:L) combined with PR:N and UI:N makes ACC instances reachable from untrusted networks an urgent patch target. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker needs network reachability to the Adobe Campaign Classic web/application tier of a vulnerable instance (7.4.3 build 9394 or earlier) and the ability to submit a request to whichever ACC feature accepts the attacker-controlled URL - the advisory does not name the specific endpoint, so any externally exposed ACC HTTP surface should be considered a candidate. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to a top-priority issue: CVSS 3.1 base score is the maximum 10.0 with AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H, meaning a remote, unauthenticated attacker with no user interaction can fully compromise confidentiality, integrity, and availability while crossing a security boundary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker reaches an internet-exposed Adobe Campaign Classic 7.4.3 (build ≤9394) endpoint and submits a crafted request that causes the ACC server to issue an attacker-chosen HTTP request; by directing that request at an internal service (cloud metadata, an internal admin API, or a deserialization-prone backend), the attacker chains the SSRF into arbitrary code execution running as the ACC service account. Because UI:N and PR:N apply, no phishing or credentials are required, and the scope change means the executed code lands outside the originally vulnerable component - likely on a backend that the ACC server is trusted to call. … |
| Remediation | Patch available per vendor advisory: upgrade Adobe Campaign Classic to the fixed build published in APSB26-66 (https://helpx.adobe.com/security/products/campaign/apsb26-66.html) - the advisory page is the authoritative source for the exact post-9394 patched build number, which was not included in the input data and should not be assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Adobe Campaign Classic instances and immediately restrict network access to trusted corporate networks using firewall rules; enable application logging. …
