Oracle Java SE contains a vulnerability that could allow a local attacker to access sensitive information on a targeted system.
The vulnerability exists because the affected software imposes insufficient security restrictions on certain files. A local attacker could exploit this vulnerability by submitting requests to access the files. Successful exploitation could allow the attacker to access the content of the files and launch further attacks.
Oracle has confirmed this vulnerability and released updated software.
Indicators of Compromise
The following Oracle products are vulnerable:
JDK and JRE 7 Update 4 and prior
JDK and JRE 6 Update 32 and prior
JDK and JRE 5.0 Update 35 and prior
SDK and JRE 1.4.2_37 and prior
The vulnerability exists because the affected software uses classes that create certain files with insecure permissions. A local attacker could exploit this vulnerability by submitting requests to these files. If successful, the attacker could gain unauthorized access to the contents of the files. The attacker could use the information to launch further attacks.
To exploit this vulnerability, the attacker must log in locally to the targeted system. This access requirement decreases the likelihood of a successful exploit.
