CVE-2003-1073

Impact by CVSS Score
  • ID: CVE-2003-1073
Summary:

A race condition in the at command for Solaris 2.6 through 9 allows local users to delete arbitrary files via the -r argument with .. (dot dot) sequences in the job name, then modifying the directory structure after at checks permissions to delete the file and before the deletion actually takes place.

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: High

Specialized access conditions exist. For example, in most configurations, the attacking party must already have elevated privileges or spoof additional systems in addition to the attacking system (e.g., DNS hijacking). The attack depends on social engineering methods that would be easily detected by knowledgeable people. For example, the victim must perform several suspicious or atypical actions. The vulnerable configuration is seen very rarely in practice. If a race condition exists, the window is very narrow.

Authentication: None

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact: None

There is no impact to the confidentiality of the system.

Integrity Impact: Partial

Modification of some system files or information is possible, but the attacker does not have control over what can be modified, or the scope of what the attacker can affect is limited. For example, system or application files may be overwritten or modified, but either the attacker has no control over which files are affected or the attacker can modify files within only a limited context or scope.

Availability Impact: None

There is no impact to the availability of the system.
