CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction	None	UI	The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

NOTE: Other versions may also be affected. ====================================================================== 2) Severity Rating: Less critical Impact: Privilege Escalation, Manipulation of Data Where: Local System ====================================================================== 3) Vendor's Description of Software Product Link: http://downloads.channel.aol.com/windowsproducts ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a security issue in AOL, which can be exploited by malicious, local users to manipulate arbitrary files. The problem is that AOL sets insecure default permissions (grants "Everyone" group "Full Control") on the "America Online 9.0" directory and all child objects. This can be exploited to remove, manipulate, and replace any of the application's files. ====================================================================== 5) Solution The vendor has issued an updated version (see the vendor statement). ====================================================================== 6) Time Table 09/02/2006 - Vendor notified. 09/02/2006 - Vendor response. 18/08/2006 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) Vendor Statement Overview AOL has recently been made aware of a local security vulnerability in the AOL client software. Upon installation, folders containing the AOL software retain local file permissions such that any local user may be able to overwrite files within the AOL program directories. A malicious user may be able to overwrite legitimate AOL software with malicious code, thereby escalating their local privileges if a privileged user were to unknowingly execute the user's software. Affected Products and Applications The following AOL software versions are affected by this issue: * All versions of the AOL client Solutions 1. AOL Members using AOL 9.0 may simply log on to AOL and a fix will be seamlessly applied to their system. 2. AOL Members using earlier versions of the AOL client are recommended to upgrade to AOL 9.0 Security Edition Acknowledgements AOL would like to thank Secunia for their assistance in responsibly addressing this issue. ====================================================================== 9) References The Common Vulnerabilities and Exposures (CVE) project has assigned candidate number CVE-2006-0948 for the vulnerability. ====================================================================== 10) About Secunia Secunia collects, validates, assesses, and writes advisories regarding all the latest software vulnerabilities disclosed to the public.
