Analysis dossierWhy It Matters
An OS command injection vulnerability exists in the device network settings functionality of reolink RLC-410W v3.0.0.136_20121102. At [1] or [2], based on DDNS type, the ddns->domain variable, that has the value of the domain parameter provided through the SetDdns API, is not validated properly. This would lead to an OS command injection. An attacker can send an HTTP request to trigger this vulnerability.
Immediate Attention
Yes
Unknown
Risk basis: CISA KEV exploitation signal; SOC ecosystem technology relevance; CRITICAL severity; Known exploitation signal from CISA KEV or ransomware metadata; Source-confirmed exploitation or CISA KEV/ransomware metadata
Affected Products & Remediation
1 source-backed product- reolink rlc-410w firmware · 3.0.0.136 20121102 · NVD CPE · Source
Vendor or catalog guidance (source)
- CISA KEV: The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization if a current mitigation is unavailable.
Known exploitation (source facts)
Only what a source states. Unknown means no source has said either way; it is not "not exploited".
- CISA KEV
- Listed
- Exploited (source statement)
- Yes
- Publicly disclosed (source)
- Unknown
CISA required action: The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization if a current mitigation is unavailable.
Suggested hunting (rule-based inference)
SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.
Matched kev-network-exposure (CVSS AV:N, CISA KEV Listed); command-injection (CWE-78)
Exposure
- Identify assets with the exact CVE and confirm the affected product/version against the advisory.Telemetry: DeviceTvmSoftwareVulnerabilities · KEV listing raises urgency, but inventory is needed to establish local exposure. · Rule kev-network-exposure
- Identify installations of the affected product and compare versions with the advisory.Telemetry: DeviceTvmSoftwareVulnerabilities · A weakness class does not establish local exposure. · Rule command-injection
Exploitation evidence
- Review relevant edge or application access logs for unusual requests around the advisory window.Telemetry: CommonSecurityLog · Log review is a hunting hypothesis; KEV listing alone does not show local exploitation. · Rule kev-network-exposure
Show more (2)
Exploitation evidence
- Review command interpreters spawned by the affected service or application.Telemetry: DeviceProcessEvents · Unexpected process lineage can support command-injection hunting. · Rule command-injection
Response
- Recheck the affected assets after the source-stated mitigation or update is applied.Telemetry: DeviceTvmSoftwareVulnerabilities · A follow-up inventory check verifies local remediation. · Rule kev-network-exposure
CISA KEV Record
The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization if a current mitigation is unavailable.
