CVE-2011-2738
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple unspecified vulnerabilities in Cisco Unified Service Monitor before 8.6, as used in Unified Operations Manager before 8.6 and CiscoWorks LAN Management Solution 3.x and 4.x before 4.1; and multiple EMC Ionix products including Application Connectivity Monitor (Ionix ACM) 2.3 and earlier, Adapter for Alcatel-Lucent 5620 SAM EMS (Ionix ASAM) 3.2.0.2 and earlier, IP Management Suite (Ionix IP) 8.1.1.1 and earlier, and other Ionix products; allow remote attackers to execute arbitrary code via crafted packets to TCP port 9002, aka Bug IDs CSCtn42961 and CSCtn64922, related to a buffer overflow.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceBuffer overflow vulnerability in multiple Cisco and EMC Ionix products allows remote attackers to execute arbitrary code via crafted packets sent to TCP port 9002. The flaw affects Cisco Unified Service Monitor, Unified Operations Manager, CiscoWorks LAN Management Solution, and various EMC Ionix products including Application Connectivity Monitor, Adapter for Alcatel-Lucent 5620 SAM EMS, and IP Management Suite.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Cisco or EMC Ionix productsReview installed software on the system for any of these product families: Cisco Unified Service Monitor, Cisco Unified Operations Manager, CiscoWorks Lan Management Solution, EMC Ionix Application Connectivity Monitor (ACM), EMC Ionix Adapter for Alcatel-Lucent 5620 SAM EMS (ASAM), or EMC Ionix IP Management SuiteAffected if Any of these products are installed
-
Check product versionLocate the version information for the installed product (typically available in the product's About dialog, installation directory, or system inventory)Affected if Version matches one of the affected versions listed in the CVE: Cisco Unified Service Monitor <= 8.5, 1.1, 2.0, 2.0.1, 2.1, 2.2, 2.3, or 8.0; Cisco Unified Operations Manager <= 8.5, 1.0, 1.1, 2.0, 2.0.1, 2.0.2, 2.0.3, 2.1, 2.2, 2.3, or 8.0; CiscoWorks LMS 3.0, 3.1, 3.2, 4.0, or 4.0.1; EMC Ionix ACM
-
Verify TCP port 9002 is listeningUse a network scanning tool or command (such as netstat, nmap, or ss) to check if TCP port 9002 is open and listening on the systemAffected if TCP port 9002 is open and the vulnerable product is installed with an affected version
Your environment is affected if any of the listed Cisco or EMC Ionix products are installed with a version matching the affected ranges AND TCP port 9002 is accessible and listening.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Cisco products version 8.6 or later and CiscoWorks LAN Management Solution 4.1 or later; apply vendor patches for EMC Ionix products. If immediate patching is not feasible, block unauthorized access to TCP port 9002 at the network perimeter.
