IBM WebSphere Advanced Server Edition 4.0.4 uses a weak encryption algorithm (XOR and base64 encoding), which allows local users to decrypt passwords when the configuration file is exported to XML.
Exploitability Analysis: Local
A vulnerability exploitable with only local access requires the attacker to have either
physical access to the vulnerable system or a local (shell) account. Examples of locally
exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and
local privilege escalations (e.g., sudo).
Exploitability Complexity: Medium
The access conditions are somewhat specialized; the following are examples:
The attacking party is limited to a group of systems or users at some level of authorization, possibly untrusted.
Some information must be gathered before a successful attack can be launched.
The affected configuration is non-default, and is not commonly configured (e.g., a vulnerability present when a
server performs user account authentication via a specific scheme, but not present for another authentication scheme).
The attack requires a small amount of social engineering that might occasionally fool cautious users (e.g.,
phishing attacks that modify a web browser’s status bar to show a false link, having to be on someone’s “buddy”
list before sending an IM exploit).
Authentication is not required to access and exploit the vulnerability.
Confidentiality Impact: Partial
There is considerable informational disclosure. Access to some system files is
possible, but the attacker does not have control over what is obtained, or the scope of
the loss is constrained. An example is a vulnerability that divulges only certain tables
in a database.
Integrity Impact: None
There is no impact to the integrity of the system.
Availability Impact: None
There is no impact to the availability of the system.
