Remote code execution lets attackers run commands on a target system, enabling full compromise; patch exposed software and restrict privileges.

Background for this topic.
Remote code execution (RCE) is the ability of an attacker to make a system run attacker-chosen code from a remote position, usually by exploiting a flaw in a network-facing application, service, protocol, or the processing of untrusted content. Unlike simple unauthorized access, successful RCE can run with the privileges of the affected process, enabling actions such as accessing data, changing configuration, disrupting a service, establishing persistence, or moving to other systems. Exploitability depends on factors including network reachability, authentication requirements, configuration, and whether execution is constrained.
Defenders should prioritize exposed RCE vulnerabilities in vulnerability management: inventory reachable assets, apply fixes or vendor mitigations, and restrict access or disable vulnerable functionality where patching is not immediately possible. Least privilege and service isolation limit the damage if exploitation succeeds. Secure input handling, safe deserialization, and avoiding unnecessary shell invocation reduce common attack paths. Monitoring for unusual process creation and outbound connections can support detection; suspected exploitation warrants prompt investigation, preservation of relevant logs, credential rotation where appropriate, and checks for persistence.
