AusCERT Security Bulletin Summary
---------------------------------
Product: Xerox FreeFlow Print Server
Operating System: Network Appliance
Impact/Access: Reduced Security -- Remote/Unauthenticated
Resolution: Patch/Upgrade
Member content until: Sunday, January 21 2018
OVERVIEW
Xerox has identified a vulnerability in its FreeFlow Print Server
v2.x on Windows product. [1]
IMPACT
Xerox has given the following details about the vulnerability:
"The current existing Xerox printers supported by the FreeFlow
Print Server platform connect to the Xerox Download Manager server
with HTTPS (port 443) over the TLS 1.0 protocol using an RSA 2048
- bit certificate with SHA1 hash and AES 256 - bit encryption. The
SHA1 encryption is a hash encryption that suffers cryptographic
weakness and its days for useful protection approaching the end.
Microsoft, Mozilla and Google have lost confidence in light of known
attacks on SHA1 encrypted data. Their Certificate Authorities will
stop issuing new SHA1 SSL certificates in 2017 in favor of stronger
encryption methods. All of the public Certificate Authorities are
moving from SHA1 to SHA2 for new SSL certificates."[1]
MITIGATION
Xerox recommends patching its affected product to the latest
version in order to fix these vulnerabilities. [1]
"The Update Manager patch is available for all currently supported
FreeFlow Print Server versions and the Xerox printer products they
support. See the supported products below:
Product Xerox Printer Product
FreeFlow Print Server 2.0 Xerox Color C60/C70 Printer
FreeFlow Print Server 2.1 Xerox iGen 5 Press
Xerox Brenva HD Production InkJet Printer"[1]
