MITRE ATT&CK
2 techniques across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires (1) valid credentials on the target device - the CVSS vector's PR:H indicates high-privilege/administrative access is needed, so this is an authenticated attack, and (2) network reachability to the AP's management/control service to deliver the crafted packets (AV:N, AC:L, no user interaction). The specific trigger is sending crafted packets containing malicious commands to the device's command-processing interface, which fails to validate input. Limiting factors that reduce real-world risk: the mandatory high-privilege credential requirement (not exploitable by an unauthenticated attacker), the need for network path to the management plane (mitigated by management-VLAN segmentation and non-exposure to the internet), and applicability only to the six listed DS-3WAP wireless AP models. |
| Impact | The signals are moderately, not maximally, alarming. CVSS is 7.2 (High) driven by AV:N/AC:L and triple-high C/I/A, but the mitigating factor is PR:H - a valid high-privilege credential is required, which substantially narrows the realistic attacker population to insiders, credential-theft scenarios, or devices left on default/weak admin passwords. No EPSS score is provided, so exploitation-probability cannot be quantified; no SSVC decision data is supplied; the vulnerability is not in CISA KEV and no POC is referenced, so there is currently no evidence of active or automatable exploitation. The description ('network', 'crafted packets') is consistent with the AV:N vector, so there is no vector-versus-description conflict to flag. Net assessment: a genuine post-authentication device-takeover risk that matters most where these APs are internet-exposed or where admin credentials are shared/weak, but absent KEV/EPSS/POC data this is not evidence of widespread opportunistic exploitation - treat as a scheduled-patch priority rather than an emergency for well-segmented, strong-credential deployments. |
| Exploit ScenarioDerived | An attacker who has obtained valid administrative credentials - for example a malicious insider, or an outsider who harvested a reused/default AP password - sends specially crafted management packets containing embedded shell commands to a reachable DS-3WAP-series access point. The insufficiently validated input is executed by the device, giving the attacker arbitrary command execution on the AP, which they can use to intercept wireless traffic, pivot into the internal network, or brick the device. No public POC is referenced, and the low attack complexity (AC:L) means that once credentials and network reach are in hand, exploitation is straightforward. |

Alert meAnalysisAIv1 – Jul 31, 2026
Authenticated command execution affects several Hikvision wireless access points (DS-3WAP521-SI, DS-3WAP522-SI, DS-3WAP621E-SI, DS-3WAP622E-SI, DS-3WAP623E-SI, DS-3WAP622G-SI), where insufficient input validation lets an attacker holding valid device credentials send crafted packets carrying malicious commands to achieve arbitrary command execution on the device. The CVSS 3.1 vector (7.2, AV:N/AC:L/PR:H/UI:N) indicates a network-reachable but high-privilege (authenticated) attack with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; the vendor has published a security advisory.
RemediationAI
Patch available per vendor advisory: apply the firmware update referenced in Hikvision's security advisory (https://www.hikvision.com/en/support/cybersecurity/security-advisory/command-execution-vulnerability-in-some-wireless-ap-products/) for each affected model; an exact fixed firmware version is not stated in the provided data, so confirm the correct build for your specific model directly from that advisory. Until patched, reduce exposure by restricting management access: place the AP management interface on an isolated management VLAN and block administrative access from user/guest and untrusted networks (trade-off: legitimate remote administration must then originate from that trusted segment), ensure the AP is never reachable from the internet, and rotate all administrative credentials to strong unique passwords to counter the PR:H prerequisite (trade-off: none material beyond operational effort). Because exploitation requires valid credentials, tightly limiting who holds AP admin accounts and monitoring device management logs for anomalous command activity are effective compensating controls.

Technical ContextAI · show details
The affected devices are Hikvision enterprise/SMB Wi-Fi access points in the DS-3WAP5xx/6xx-SI product family, embedded network appliances running a proprietary management firmware that accepts administrative/control packets over the network. The root cause is insufficient input validation on data contained in these crafted packets: attacker-supplied content is passed into an underlying command or shell context without adequate sanitization, permitting OS command injection (CWE-78-class behavior, although the input lists CWE as N/A). Because access points typically run their management services as a privileged system account, injected commands execute with elevated rights on the embedded OS. The CPE set precisely scopes the affected models to six application-level Hikvision AP identifiers, but no firmware version boundaries are provided in the CPE strings.

DescriptionCVE.org
Some Hikvision Wireless Access Points are vulnerable to authenticated command execution due to insufficient input validation. Attackers with valid credentials can exploit this flaw by sending crafted packets containing malicious commands to affected devices, leading to arbitrary command execution.
Executive ViewAI
Hikvision wireless access points in enterprise networks (DS-3WAP521-SI, DS-3WAP522-SI, DS-3WAP621E-SI, DS-3WAP622E-SI, DS-3WAP623E-SI, DS-3WAP622G-SI) are vulnerable to complete infrastructure compromise through authenticated remote command execution, creating a direct pathway for insider threats and credential-based attacks. With no vendor patch available, this exposure window remains indefinite, requiring immediate compensating controls. Leadership must prioritize securing administrator access to these devices and establish a remediation timeline aligned with eventual firmware updates.
Isolate access points from critical systems using network segmentation; restrict administrative access to allowlisted IP addresses and enforce multi-factor authentication where supported; disable remote management and permit only local administration over secure channels; deploy network monitoring to detect anomalous command execution patterns on affected devices; maintain an audit log of all administrative access and configuration changes.
