[原文]AOL 9.0 Security Edition revision 4184.2340, and probably other versions, uses insecure permissions (Everyone/Full Control) for the "America Online 9.0" directory, which allows local users to gain privileges by replacing critical files.
AOL Directory Permission Weakness Local Privilege Escalation
Local Access Required
Loss of Integrity
AOL contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered due to default permissions that grants 'Everyone' group 'Full Control' to the 'America Online 9.0' directory. This flaw may lead to a loss of integrity.
Currently, there are no known workarounds or upgrades to correct this issue. However, AOL has released a patch to address this vulnerability.
AOL Security Edition is prone to a local privilege-escalation vulnerability.
This vulnerability arises because of insecure default permissions associated with directories, which can allow local attackers to place arbitrary executables in a directory that may be executed with elevated privileges.
AOL Security Edition 9.0 is reported vulnerable; other versions may be affected as well.
An exploit is not required.
AOL has released fixes to address this issue. These fixes can be automatically applied by logging in to the service.
