CVE-2009-1520
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 · uneditedBuffer overflow in the Web GUI in the IBM Tivoli Storage Manager (TSM) client 5.1.0.0 through 5.1.8.2, 5.2.0.0 through 5.2.5.3, 5.3.0.0 through 5.3.6.4, 5.4.0.0 through 5.4.2.6, and 5.5.0.0 through 5.5.1.17 allows attackers to cause a denial of service (application crash) or execute arbitrary code via unspecified vectors.
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 · high confidenceBuffer overflow vulnerability in the IBM Tivoli Storage Manager client Web GUI across multiple version ranges (5.1.x through 5.5.1.x). The flaw allows attackers to cause denial of service via application crash or potentially execute arbitrary code through unspecified vectors.

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.
-
Check if IBM Tivoli Storage Manager client is installedLook for TSM client binaries (dsmadmc, dsmc) in common installation directories such as C:\Program Files\Tivoli\TSM on Windows or /opt/tivoli/tsm on Unix/Linux. Check for the TSM client service or process running on the system.Affected if TSM client software is present on the system
-
Identify the installed TSM client versionRun the version command for the TSM client. On Windows, use 'dsmadmc -v' or check the program's properties. On Unix/Linux, run 'dsmc -v' or check /opt/tivoli/tsm/client/ba/bin/dsmc -v. Alternatively, check the Windows Registry under HKLM\SOFTWARE\IBM\Tivoli\StorageManager\Client\CurrentVersion or inspect version files in the installation directory.Affected if The installed version falls within 5.1.x through 5.3.6.4, or specifically matches any of these: 5.1, 5.1.8.0, 5.1.8.2, 5.2, 5.2.5.1, 5.2.5.2, 5.2.5.3, 5.3, 5.3.5.2, 5.3.5.3, 5.3.6.3, 5.3.6.4, or Express versions 5.3, 5.3.3.0, 5.3.6.4
-
Verify if the Web GUI component is enabledCheck the TSM client configuration files (dsm.opt, dsm.sys) for Web GUI settings. On Windows, the Web GUI typically runs as a Windows service (TSM Web Client or similar). Check Windows Services or run 'sc query' to find TSM web client services. On Unix/Linux, look for webgui processes or check for configuration in the client directory.Affected if The Web GUI interface (web client service) is installed and running on the system
-
Confirm Web GUI accessibilityTest network connectivity to the Web GUI port (default HTTP port 1580 or HTTPS port 1581). Use a browser to access http://hostname:1580 or https://hostname:1581 if the service is running. Check firewall rules to determine if the Web GUI port is exposed.Affected if The Web GUI is accessible over the network, increasing exposure to potential exploitation
A user is affected if the IBM Tivoli Storage Manager client is installed with a version between 5.1 and 5.3.6.4 (or matching the specific versions listed) AND the Web GUI component is enabled and accessible.

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 dataApply vendor patches (version 5.5.1.18 or later, or migrate to supported TSM version) to address the buffer overflow in the Web GUI component; if patching is not immediately feasible, disable the Web GUI interface and restrict network access.
