CVE-2011-2405
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 HP ProLiant SL Advanced Power Manager (SL-APM) with firmware before 1.20 does not properly validate users, which allows remote attackers to cause a denial of service 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 · moderate confidenceHP ProLiant SL Advanced Power Manager (SL-APM) firmware versions prior to 1.20 contain an improper user validation vulnerability that allows remote attackers to cause denial of service. The exact attack vector is unspecified in available documentation, but the vulnerability is exploitable remotely without authentication.

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 if HP ProLiant SL Advanced Power Manager is deployedCheck your infrastructure inventory or physically locate the SL-APM module in HP ProLiant SL chassis. The SL-APM is a power management controller card installed in the chassis.Affected if The product is present in the environment - all versions of HP ProLiant SL Advanced Power Manager are affected by this vulnerability.
-
Check SL-APM firmware versionAccess the SL-APM management interface (typically through the iLO or chassis management IP) and navigate to the firmware or version information section. Alternatively, use the HP SUM (Smart Update Manager) to scan the firmware version.Affected if Firmware version is 1.11 or lower, or specifically version 1.10. Versions prior to 1.20 are affected; version 1.20 and later are fixed.
-
Verify remote access configurationCheck the network configuration of the SL-APM management interface. Determine if the management port is directly accessible from network segments outside the trusted management network.Affected if The SL-APM management interface is exposed to untrusted network segments or the internet without firewall filtering.
-
Review for authentication enforcementExamine the SL-APM web interface or CLI for authentication settings. Attempt to access the management URL without credentials to confirm whether authentication is enforced.Affected if The interface allows unauthenticated access or authentication can be bypassed, confirming the improper user validation flaw.
A user is affected if HP ProLiant SL Advanced Power Manager is present in their environment (all versions contain the flaw) and the management interface is network-accessible, with firmware versions prior to 1.20 confirming the specific vulnerable state.

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 dataUpdate SL-APM firmware to version 1.20 or later. If immediate patching is not possible, restrict network access to the power management interface using network segmentation or firewall rules to limit exposure to untrusted networks.
