This is not a late April Fool's joke: After #37C3, we accidentally dumped the keypad codes of almost half of an IBIS hotel's rooms by entering some dashes into a check-in terminal: https://www.pentagrid.ch/en/blog/ibis-hotel-check-in-terminal-keypad-code-leakage/ #itsecurity #infosec #ibis #accor #terminal #hotel

At Pentagrid, we occasionally review our clients' internal processes to identify IT security risks. When we discovered that large sums of money are transferred with just a few clicks and no transaction verification, we helped securing the process. At the same time, we developed a tool to support this improvement. #itsecurity #infosec #iso200222 #pain001 https://www.pentagrid.ch/en/blog/pain001-interfaces-and-payment-of-your-salary/
We analysed the security of a #WindRiver #VxWorks (the operating system running also on NASA's Curiosity mars rover) embedded device and found a critical vulnerability in the #tarExtract function: https://www.pentagrid.ch/en/blog/wind-river-vxworks-tarextract-directory-traversal-vulnerability/ #itsecurity #infosec #pentesting #cisa #vxworks
Today, our certificate transparency monitoring popped up with an InvalidSignature exception, because we didn't add the recent Let's Encrypt intermediate CAs as monitoring trust anchors. We updated the documentation accordingly, but it is good to see it working. If you want to monitor your certificates, you may run your own instance. https://github.com/pentagridsec/check-transparency-logs

Summer is clearly over and silly season, too. We saw neither alligators in the swimming lake nor lions in town, but a a snake curling through the infrastructure. It was a #python. A few email-related Python libraries do not check server certificates. It is nothing new, but still a bit surprising in 2023 and not everyone got the memo.

Our colleague Michael will be speaking about #Unify #OpenScape and #OpenStage #VoIP phones at the #Area41 security conference in Zurich on June 6. If you use these VoIP systems, we recommend coming to the talk.

Pentagrid published two #Hackvertor tags for #EAN13 (also Swiss AHV numbers) and #TOTP for #2FA. These tags are available via the Hackvertor Tag Store by @garethheyes@bird.makeup. Our blog post explains what these tags do and how they can be used. https://www.pentagrid.ch/en/blog/hackervertor-ean13-and-totp-tags-for-web-application-penetration-testing-with-burp/ #pentest #OWASP

I think a 9.0 for CVS-2023-42629 is a bit overrated, because of PR:L, but anyway Liferay publishes an advisory for this: https://liferay.dev/portal/security/known-vulnerabilities/-/asset_publisher/jekt/content/cve-2023-42629

If you want to protect your IT #infrastructure against #MITM attacks where an attacker bypasses domain verification to obtain valid certificates, you may want to use #CAA and #accountURI binding, which is easy to set up. https://www.pentagrid.ch/en/blog/domain-verification-bypass-prevention-caa-accounturi/ #hardening
It happened again. We accidentally broke another #hotel check-in #terminal.
