CVE-2008-2158: EMC AlphaStor Server Agent CLI stack buffer overflow

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

critical priorityCVSS 2.0 base score of 10 with network reachability, no authentication, and full confidentiality, integrity, and availability impact.

What it is

The Command Line Interface process in the EMC AlphaStor 3.1 SP1 Server Agent for Windows contains multiple stack-based buffer overflows. Crafted TCP packets sent to port 41025 can overwrite stack memory and lead to arbitrary code execution. The flaw is remotely reachable without authentication, making it a serious exposure for any host running the affected agent.

Impact

A remote attacker can execute arbitrary code with the privileges of the Server Agent process, potentially gaining full control of the affected Windows host.

Attack surface

Reachable over the network via TCP port 41025; the CVSS vector AV:N/AC:L/Au:N indicates no authentication and no user interaction are required.

Exploitation

Not listed in CISA KEV and no ransomware associations are documented. EPSS is high (0.58397, 99th percentile), and references include a vendor advisory but no public exploit tag, so active exploitation is plausible but unconfirmed.

What to do

• Apply the EMC vendor patch or upgrade AlphaStor beyond 3.1 SP1 as soon as possible.
• Restrict network access to TCP port 41025 to trusted management hosts only.
• Segment or isolate systems running the AlphaStor Server Agent from untrusted networks.
• Monitor vendor advisories for updated guidance if the product is no longer supported.

Detection

• Monitor network traffic to TCP port 41025 for oversized or malformed packets targeting the Server Agent.
• Inspect host logs for unexpected crashes or restarts of the AlphaStor CLI/Server Agent process.
• Watch for anomalous child processes or command execution originating from the Server Agent service account.
