Synopsis

The remote multi-function device is affected by multiple vulnerabilities.

Description

According to its model number and software version, the remote Xerox WorkCentre 4260 / 4265 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 man-in-the-middle vulnerability, known as Logjam, exists due to a flaw in the SSL/TLS protocol. A remote attacker can exploit this flaw to downgrade connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. (CVE-2015-4000)

- A TCP connection spoofing vulnerability exists due to weak TCP initial sequence number (ISN) generation. A man-in-the-middle attacker can exploit this to spoof TCP connections or cause a denial of service.
(CVE-2015-3963)

Note that the FREAK (CVE-2015-0204) vulnerability on WorkCentre 4260 was fixed in a prior release.
