CVE-2007-5323
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 · uneditedThe RepliStor Server Service in EMC Replistor 6.1.3 allows remote attackers to execute arbitrary code via a size value that causes RepliStor to create a smaller buffer than expected, which triggers a buffer overflow when that buffer is used in a recv function call.
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 confidenceEMC Replistor 6.1.3 contains a buffer overflow vulnerability in the RepliStor Server Service. The vulnerability is triggered when a remote attacker sends a specially crafted size value that causes the service to allocate a smaller buffer than expected. When the service subsequently uses the recv function to copy data into this undersized buffer, a buffer overflow occurs, allowing remote arbitrary code execution.

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.
-
Confirm EMC Replistor installationLook for Replistor installation directories or check for RepliStor service entry in system services list using 'services.msc' or 'sc query' commandAffected if Replistor software is present on the system
-
Verify Replistor versionCheck the installed version of EMC Replistor by inspecting the product's About dialog, version file in the installation directory, or using the product's version information command if availableAffected if Installed version is exactly 6.1.3
-
Check RepliStor Server Service statusOpen Services control panel or run 'sc query RepliStor' to determine if the RepliStor Server Service is installed and runningAffected if RepliStor Server Service is installed and currently running
-
Confirm network exposure of the serviceUse 'netstat -an' or a port scanner to check if the RepliStor service port is listening on network interfaces, particularly on interfaces accessible from untrusted networksAffected if The RepliStor Server Service is listening on a network-accessible port
The environment is affected if EMC Replistor version 6.1.3 is installed with the RepliStor Server Service running and exposed to network access.

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 dataIf a vendor patch is available, apply it immediately. If no patch exists due to EOL status, consider network isolating the RepliStor service, disabling it if not business-critical, or implementing compensating controls such as firewall rules restricting access to the service port.
