CVE-2026-7705 Overview
CVE-2026-7705 is a command injection vulnerability in JD Cloud JDCOS version 4.5.1.r4518. The flaw resides in the set_iptv_info function within the /jdcap endpoint of the Service Interface component. Attackers can manipulate the vid argument to inject arbitrary operating system commands. The issue is classified under [CWE-74] for improper neutralization of special elements in output used by a downstream component.
The attack is exploitable remotely and requires low privileges. A public exploit has been released. The vendor was contacted prior to disclosure but did not respond.
Critical Impact
Remote authenticated attackers can inject operating system commands through the vid parameter, leading to unauthorized command execution on affected JDCOS deployments.
Affected Products
- JD Cloud JDCOS 4.5.1.r4518
- Service Interface component (/jdcap endpoint)
- set_iptv_info function handler

Technical Details for CVE-2026-7705
Vulnerability Analysis
The vulnerability resides in the set_iptv_info function exposed through the /jdcap Service Interface in JD Cloud JDCOS 4.5.1.r4518. The function processes the vid argument without sufficient input neutralization. An attacker who controls the vid value can append shell metacharacters to inject additional commands into the underlying system call.
Because the endpoint is reachable over the network and only requires low privileges, exploitation does not depend on local access or user interaction. The vulnerability falls under [CWE-74], covering injection flaws where untrusted input is passed into a downstream interpreter.
Root Cause
The root cause is missing or insufficient sanitization of the vid parameter before it is incorporated into a system command. JDCOS does not properly escape shell metacharacters such as ;, |, &, or backticks. When the function builds and executes the command, attacker-supplied content is interpreted as part of the command string rather than as data.
Attack Vector
A remote attacker with low-level credentials sends a crafted request to the /jdcap endpoint targeting the set_iptv_info handler. The vid parameter carries a payload containing shell metacharacters and an attacker-chosen command. The JDCOS process executes the resulting command in the context of the service account.
The vulnerability has an EPSS probability of 1.058% (77.7 percentile), and a public proof-of-concept has been published. Refer to the VulDB Vulnerability #360881 entry and the VulDB CTI for #360881 for technical exploitation details.
Detection Methods for CVE-2026-7705
Indicators of Compromise
- HTTP requests to /jdcap containing shell metacharacters (;, |, &, `, $()) inside the vid parameter.
- Unexpected child processes spawned by the JDCOS Service Interface process, especially shells (sh, bash) or networking tools (curl, wget, nc).
- Outbound connections from JDCOS hosts to unknown external IP addresses immediately following access to the set_iptv_info endpoint.
Detection Strategies
- Inspect web and reverse-proxy logs for set_iptv_info calls with non-alphanumeric values in vid.
- Apply behavioral process-tree analytics that flag the JDCOS service binary spawning interactive shells or scripting interpreters.
- Correlate authentication events with subsequent /jdcap requests to identify low-privileged accounts performing administrative operations.
Monitoring Recommendations
- Forward JDCOS application logs and host process telemetry to a central SIEM for correlation across web, host, and network layers.
- Alert on JDCOS-originated commands invoking cmd.exe, powershell, /bin/sh, or download utilities.
- Track baseline traffic to /jdcap and trigger investigation on volume spikes or new source IP ranges.
How to Mitigate CVE-2026-7705
Immediate Actions Required
- Restrict network exposure of the /jdcap Service Interface to trusted management networks only.
- Audit and reduce accounts with access to the set_iptv_info function to the minimum required.
- Hunt for prior exploitation by reviewing process and command history on JDCOS hosts.
Patch Information
No vendor patch has been published. According to the disclosure, JD Cloud was contacted but did not respond. Monitor the VulDB Submission #805644 and JD Cloud advisories for updates. Until a fix is released, defenders should rely on compensating controls.
Workarounds
- Place a web application firewall in front of /jdcap and block requests where vid contains shell metacharacters.
- Run the JDCOS service under a least-privileged account to limit the impact of injected commands.
- Disable or firewall the set_iptv_info route if IPTV configuration is not required in the deployment.
- Apply egress filtering on JDCOS hosts to block outbound connections to non-approved destinations.
