Dell Container Storage Modules: Missing authorization in csireverseproxy
Summary
Dell Container Storage Modules (CSM) prior to version 1.18.0 contain a missing authorization flaw in the csireverseproxy component of the Dell CSI Driver for PowerMax. An unauthenticated attacker with adjacent network access could potentially gain unauthorized access. The flaw is addressed in Dell security update DSA-2026-448, which also fixes several more severe CSM vulnerabilities.
Affected
- Dell Container Storage Modules versions prior to 1.18.0
- Component: Dell CSI Driver for PowerMax (csireverseproxy)
Fixed in
- Upgrade to Dell Container Storage Modules version 1.18.0 or later
Workaround
- Unknown. Dell lists no workaround; upgrading is the only documented fix.
- Until patched, limit which hosts and networks can reach the reverse proxy.
Exploitation
- No known exploitation at the time of writing.
- Not listed in CISA KEV.
- No public proof of concept found.
Our recommendation
- Check whether Kubernetes clusters use the Dell CSI Driver for PowerMax.
- Upgrade to version 1.18.0 or later as part of DSA-2026-448.
- Restrict network access to the reverse proxy until patched.
- Rotate the JWT signing secret after upgrading.
- Verify the CVSS score in NVD, as third-party sources report different values.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
