Lifecycle Timeline

CWE-617 Reachable Assertion vulnerability exists that could allow an authenticated attacker to trigger a denial-of-service condition, impacting system availability when a specially crafted request is sent to a vulnerable network-exposed service.
AnalysisAI
Denial-of-service in Schneider Electric PowerLogic P7 power monitoring devices allows an authenticated attacker to crash a network-exposed service by sending a specially crafted request that triggers a reachable assertion (CWE-617), fully disrupting availability. The CVSS 4.0 score of 6.9 reflects the high-privilege prerequisite (PR:H) that constrains exploitation to actors with administrative credentials, while the availability impact is rated high (VA:H) with no confidentiality or integrity consequences. No public exploit code and no active exploitation via CISA KEV have been identified at time of analysis.
Technical ContextAI
CWE-617 (Reachable Assertion) describes a code path in which an internal assertion statement - typically a developer-inserted sanity check - can be reached and triggered by attacker-controlled input, causing the process to abort rather than handle the condition gracefully. In the PowerLogic P7, a Schneider Electric industrial power monitoring unit, a network-exposed service fails to sanitize or bound-check input before evaluating such an assertion. The CPE string cpe:2.3:a:schneider_electric:powerlogic™_p7:*:*:*:*:*:*:*:* with a wildcard version field indicates the flaw spans the entire known product line. This is an OT/ICS-class device typically deployed in electrical distribution panels and substations, where service availability directly affects operational continuity.
RemediationAI
Consult Schneider Electric advisory SEVD-2026-160-03 (https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2026-160-03&p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2026-160-03.pdf) for patched firmware versions - no exact fix version is independently confirmable from the available data. As compensating controls pending patching: restrict network access to the PowerLogic P7 management interface using firewall rules or VLAN segmentation to limit exposure to trusted OT management networks only; enforce least-privilege access by auditing and reducing the number of accounts holding high-privilege credentials to the device; implement session monitoring and alerting for anomalous authenticated request patterns targeting the device's network service. Note that network segmentation alone does not eliminate the risk if a threat actor already holds valid high-privilege credentials.
