  • Route RPKI validation April 1st, 2022
    RPKI is a security framework by which network owners can validate and secure the critical route updates or Border Gateway Protocol (BGP) announcements between public Internet networks. BGP is essentially the central nervous system of the Internet and one of its fundamental building blocks. The main function of BGP is to facilitate efficient routing between Autonomous Systems (AS), by building and maintaining the Internet routing table. The Internet routing table is effectively the navigation system of the Internet and without it, traffic would be unable to flow between its constituent networks. Unfortunately, routing equipment alone cannot distinguish between legitimate and malicious routing announcements,...
  • RIPE – Atlas Anchor February 17th, 2022
    We have become an even more integral part of the RIPE Atlas project by hosting an anchor, a device that allows for latency analysis of traffic between autonomous systems. Atlas anchors play an integral role in the RIPE Atlas network by acting both as enhanced RIPE Atlas probes with more measurement capacity, as well as regional measurement targets within the greater RIPE Atlas network. Anchors are able to perform many more measurements than a regular RIPE Atlas probe, and the large amount of data they collect is made available to everyone. In addition, anchors act as powerful targets that can...
  • MANRS June 20th, 2020
    GOLINE firmly believes in initiatives to protect networks, improve security and resilience of the global routing system. Therefore we decided to support the MANRS project and join as participants.Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that provides crucial fixes to reduce the most common routing threats. MANRS offers specific actions via four programs for Network Operators, Internet Exchange Points, CDN and Cloud Providers, and Equipment Vendors. Requirements for Participation Please read the full MANRS Actions document before applying. You can become a participant if you meet these requirements: You (or your company) support...

Cisco remediation COP files remain stuck

Caparrelli Paolo Cisco 26 January 2024

Recently, a Cisco bulletin was released to inform about severe security vulnerabilities.

Unified Communications Manager (Unified CM) (CSCwd64245)
Unified Communications Manager IM & Presence Service (Unified CM IM&P) (CSCwd64276)
Unified Communications Manager Session Management Edition (Unified CM SME) (CSCwd64245)
Unified Contact Center Express (UCCX) (CSCwe18773)
Unity Connection (CSCwd64292)
Virtualized Voice Browser (VVB) (CSCwe18840)

As usual, we immediately applied the patches through the COP files found on the Cisco website in the download section for each product.
The installation was successfully completed, but the task on all Cisco products (CUCM, CUC, CUPS, UCCX) remains stuck.
Obviously, there's no way to stop it because the installation of the COP files is managed by two semaphore files named /var/log/install/upgrade_status.xml and under /tmp, the file upgradeState.ser.
We tried from the console, in CLI, to stop the installation, but there's no way, not even by rebooting the virtual appliance.

The only way is to enter as a superuser (rooted) and execute the following commands:

utils remote_account enable
utils remote_account create ciscotac 3
(You don't need it if your VA is already rooted)

cd /var/log/install/
mv upgrade_status.xml upgrade_status.xml.orig
rm -rf /var/log/install/upgrade_status.xml
cd /tmp
rm – f upgradeState.ser

utils remote_account disable
