Yes. CISA added CVE-2018-7602 to its Known Exploited Vulnerabilities catalogue on 13 April 2022, which it does only when there is reliable evidence of active exploitation. CISA lists it as known to be used in ransomware campaigns. A remote code execution vulnerability exists within multiple subsystems of Drupal that can allow attackers to exploit multiple attack vectors on a Drupal site.
How to interpret “being exploited in the wild” for CVE-2018-7602
For this CVE, “in the wild” means active exploitation has been observed well enough for CISA to list it in the Known Exploited Vulnerabilities catalogue. That changes the question from “is there a theoretical flaw?” to “is there confirmed exposure that needs operational action now?” The answer should be treated as a live prioritization signal, not a historical footnote.
Because Drupal Core is a widely deployed web platform, exploitation can affect internet-facing sites directly and quickly. The practical implication is that exposed Drupal instances should be treated as high priority until you have confirmed remediation and ruled out signs of compromise.
For authoritative tracking, use the CISA Known Exploited Vulnerabilities Catalog and the NIST National Vulnerability Database to anchor your response in the current record rather than secondary reporting.
What the Drupal RCE exposure means operationally
The material issue is not just that Drupal Core contains a remote code execution condition, but that the vulnerability sits in multiple subsystems and can be reached through multiple attack vectors. That broadens the exposure surface and makes simple assumptions about one protected entry point less reliable.
If a site is internet-facing, the main operational questions are whether the vulnerable code path exists anywhere in the deployed stack, whether the instance was reachable during the exposure window, and whether any attacker activity could have used that foothold to run arbitrary code on the server.
Related exploit tracking and remediation context is covered by the Zero-Day and Exploited Vulnerabilities Guide, which is useful when a flaw has crossed from disclosure into active exploitation.
What to do if patching cannot happen immediately
When patching is delayed, the priority shifts to reducing exposure and limiting the attacker’s ability to use the application as a launch point. That usually means shrinking public reachability, tightening web application controls, and watching for suspicious server-side changes, new admin activity, unexpected outbound connections, or webshell-style persistence.
Do not treat delay as passive risk acceptance. A live exploited CVE warrants temporary compensating controls, rapid inventory of exposed instances, and a clear owner for emergency remediation. If the system is business-critical, the fallback plan should be explicit before the next maintenance window arrives.
If you need a broader playbook for urgency, verification, and post-patch hunting, the Vulnerability Management Guide provides the prioritization logic that should drive decision-making here.
Risk and Threat Considerations
Active exploitation means the risk is not limited to service disruption. A Drupal RCE can give an attacker server-side execution, which can be used for credential theft, content tampering, malware staging, lateral movement, or further compromise of adjacent systems.
Failure mechanism: The attacker reaches a vulnerable Drupal code path, triggers execution on the web server, and then uses that foothold to run commands, drop files, or pivot into the surrounding environment.
Impact: The site can move from a software vulnerability to a full hosting compromise, with the possibility of data exposure, defacement, persistence, and broader network abuse.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5, CIS Controls v8 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-2 — Flaw Remediation | Active exploited CVE response depends on rapid vulnerability remediation. |
| RA-5 — Vulnerability Monitoring and Scanning | You need continuous exposure discovery and validation for internet-facing Drupal assets. | |
| IR-4 — Incident Handling | Confirmed exploitation requires containment, compromise assessment, and response coordination. | |
| Recommendation — Prioritise SI-2 to remediate the Drupal flaw and verify closure across all exposed instances. Use RA-5 to identify vulnerable Drupal instances and confirm remediation status. Apply IR-4 to investigate likely compromise and coordinate containment if exploitation is suspected. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | This CVE is an exploited vulnerability that needs prioritized remediation and verification. |
| CIS-17 — Incident Response Management | Active exploitation can require incident response if compromise indicators appear. | |
| Recommendation — Use CIS-7 to identify, prioritise, and remediate exposed Drupal systems quickly. Use CIS-17 to investigate, contain, and recover if exploitation evidence is found. | ||
| OWASP ASVS | V13 — Configuration | Drupal exposure often hinges on secure deployment and hardening of application configuration. |
| Recommendation — Apply V13 to harden the Drupal deployment and reduce exploitable exposure paths. | ||
Practitioner Guidance
What to verify: Confirm whether every Drupal instance in scope is actually exposed, not just whether a patch is available. An accurate asset inventory matters here because a single forgotten internet-facing site can remain exploitable after the main environment is fixed.
Decision rule: If the system is reachable from the internet and the CVE is still open, treat remediation as urgent production work, not routine maintenance. If patching must wait, document the compensating control, the exception owner, and the earliest valid removal date.
What to measure: Track time to identify exposed instances, time to remediate, and time to confirm no signs of compromise after exposure was discovered. Those three measures tell you whether the response is operationally real or merely procedural.
Practitioner takeaway: For a KEV-listed Drupal RCE, the correct response is to assume active attacker interest until proven otherwise, then combine exposure confirmation, rapid fix deployment, and compromise assessment in one workstream.
