CVE-2024-38325 Overview
CVE-2024-38325 affects IBM Storage Defender versions 2.0.0 through 2.0.7. The defender-sensor-cmd command-line interface (CLI) on the on-prem defender component transmits network requests over an insecure channel. A remote attacker positioned between the client and server can intercept this traffic and recover sensitive information using man-in-the-middle (MITM) techniques.
The weakness is categorized under [CWE-311] Missing Encryption of Sensitive Data. IBM published advisory details on the IBM Support Page.
Critical Impact
An unauthenticated network attacker can intercept CLI communications and harvest sensitive data exchanged by the defender-sensor-cmd component.
Affected Products
- IBM Storage Defender 2.0.0
- IBM Storage Defender versions 2.0.1 through 2.0.6
- IBM Storage Defender 2.0.7

Technical Details for CVE-2024-38325
Vulnerability Analysis
The defender-sensor-cmd CLI in IBM Storage Defender issues network requests without enforcing encrypted transport. Data leaves the host in cleartext or with insufficient cryptographic protection. An attacker on the network path observes the traffic and reads credentials, tokens, or operational metadata transmitted by the sensor.
This is an information disclosure flaw, not a remote code execution or integrity issue. The impact targets confidentiality of data exchanged between the sensor and backend services. The EPSS probability of 0.247% reflects low predicted exploitation activity, but the vulnerability is fully network-reachable without authentication.
Root Cause
The root cause is [CWE-311] Missing Encryption of Sensitive Data. The defender-sensor-cmd client sends requests over a channel that does not provide confidentiality. Either Transport Layer Security (TLS) is not negotiated, certificate validation is incomplete, or sensitive payloads are emitted before the secure channel is established. Any of these conditions exposes the payload to a passive or active network observer.
Attack Vector
An attacker must occupy a network position between the defender sensor and its remote endpoint. Common scenarios include compromised network infrastructure, rogue Wi-Fi access points, Address Resolution Protocol (ARP) spoofing on a shared segment, or upstream routing manipulation. Once positioned, the attacker captures traffic with standard packet capture tools and extracts the cleartext fields. Active MITM attackers can also proxy the connection to harvest credentials in real time.
No exploitation code is publicly available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2024-38325
Indicators of Compromise
- Unexpected defender-sensor-cmd outbound connections to non-standard destinations or ports
- Plaintext payloads containing sensor identifiers, tokens, or configuration data observed in network captures
- ARP table anomalies or duplicate MAC addresses near hosts running IBM Storage Defender
- Certificate warnings or downgraded TLS sessions logged on hosts running the defender sensor
Detection Strategies
- Inspect network traffic from defender hosts for HTTP or other unencrypted protocols originating from the defender-sensor-cmd process
- Correlate process telemetry with network flows to flag sensor communications that bypass TLS
- Deploy network detection rules that alert on cleartext credentials or API tokens leaving sensor hosts
Monitoring Recommendations
- Log all egress connections from IBM Storage Defender hosts and baseline expected destinations
- Enable TLS inspection at network egress points to verify the sensor uses encrypted channels
- Monitor for ARP spoofing and rogue gateway activity on segments hosting Storage Defender components
- Review IBM Storage Defender audit logs for connection failures that may indicate MITM tampering
How to Mitigate CVE-2024-38325
Immediate Actions Required
- Upgrade IBM Storage Defender to the fixed release identified in the IBM Support advisory
- Restrict the network segments that carry defender-sensor-cmd traffic to trusted, segmented VLANs until patched
- Rotate any credentials, API tokens, or certificates that may have been transmitted by affected sensors
- Enable network segmentation and 802.1X controls to reduce opportunities for MITM positioning
Patch Information
IBM has published remediation guidance on the IBM Support Page. Administrators running IBM Storage Defender 2.0.0 through 2.0.7 should review the advisory and apply the vendor-supplied fix. Confirm the upgraded sensor negotiates TLS with valid certificate validation after deployment.
Workarounds
- Route defender-sensor-cmd traffic through an IPsec or TLS-terminating tunnel to add transport encryption until the patch is applied
- Isolate sensor hosts on management VLANs with strict access control lists to limit MITM exposure
- Enforce mutual TLS at upstream proxies that front the defender backend where the configuration supports it
