AusCERT Week in Review for 9th April 2021
Greetings,
Welcome back from the Easter long weekend.
This week we kicked things off by releasing a blog piece on the topic of the recent Facebook data leak of over five-hundred million of its users. We’d be remiss not to mention the good work done by the folks from Have I Been Pwned in this particular instance.
Tune in next week and join our Director, Dr. David Stockdale as he discusses the focus on securing remote access as a key step in the zero-trust journey. “Securing the people, systems, and assets in a higher education org is no small task. With over fifty-thousand students supported by over seven-thousand staff members, learn why UQ chose Duo Security as its 2FA solution.” For further details on the webinar and to register, please visit the AusCERT website here.
Members – another reminder that all nominated Primary and Organisation contact person(s) would have received details regarding your organisation’s member token(s), part of your AusCERT membership perks which allows you to attend our annual conference for free or as a partially subsidised delegate, please make sure you utilise the token(s) by midnight on Sunday 18 April! Conference registrations can be completed via our website here.
Until next week, have a good weekend everyone.
Cisco fixes bug allowing remote code execution with root privileges
Date: 2021-04-07
Author: Bleeping Computer
Cisco has released security updates to address a critical pre-authentication remote code execution (RCE) vulnerability affecting SD-WAN vManage Software’s remote management component.
The critical security flaw tracked a CVE-2021-1479 which received a severity score of 9.8/10. It allows unauthenticated, remote attackers to trigger a buffer overflow on vulnerable devices in low complexity attacks that don’t require user interaction.
“An attacker could exploit this vulnerability by sending a crafted connection request to the vulnerable component that, when processed, could cause a buffer overflow condition,” Cisco explained.
The company fixed two other high-severity security vulnerabilities in the user management (CVE-2021-1137) and system file transfer (CVE-2021-1480) functions of the same product allowing attackers to escalate privileges.
Successful exploitation of these two bugs could allow threat actors targeting them to obtain root privileges on the underlying operating system.

Contact books of Australian diplomats hacked in major ‘phishing’ scam
Date: 2021-04-07
Author: Sydney Morning Herald
Senior Australian diplomats, including United States ambassador Arthur Sinodinos, have been caught up in a sophisticated identity theft scam in which cyber attackers impersonated them on encrypted messaging services WhatsApp and Telegram in a bid to get sensitive information from their contacts.
Under the scam, senior politicians and diplomats are being sent messages asking them to validate new WhatsApp and Telegram accounts. Once they click on the link or download the app, the hacker then has access to their contact book and the ability to impersonate them on the new account.
