New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 8.9
SynopsisThe remote multi-function device is affected by multiple vulnerabilities.
DescriptionAccording to its model number and software version, the remote Xerox WorkCentre 77XX device is affected by multiple vulnerabilities :
- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)
- A heap-based buffer overflow condition exists in the GNU C Library (glibc) due to improper validation of user-supplied input to the glibc functions
__nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. This vulnerability is known as GHOST. (CVE-2015-0235)
