Steinar H Gunderson ☛ GS1900-10HP web session hijack
While fiddling around, I found a (fairly serious) vulnerability in Zyxel's GS1900-10HP and related switches; today Zyxel released an advisory with updated firmware, so I can publish my side of it as well. (Unfortunately there's no Zyxel bounty program, but Zyxel PSIRT has been forthcoming all along, which I guess is all you can hope for.)

37signals LLC ☛ Passwords have problems, but passkeys have more
We had originally planned to go all-in on passkeys for ONCE/Campfire, and we built the early authentication system entirely around that. It was not a simple setup! Handling passkeys properly is surprisingly complicated on the backend, but we got it done. Unfortunately, the user experience kinda sucked, so we ended up ripping it all out again.
The problem with passkeys is that they're essentially a halfway house to a password manager, but tied to a specific platform in ways that aren't obvious to a user at all, and liable to easily leave them unable to access of their accounts. Much the same way that two-factor authentication can do, but worse, since you're not even aware of it.

Krebs On Security ☛ Bug Left Some Windows PCs Dangerously Unpatched
Satnam Narang, senior staff research engineer at Tenable, said that while the phrase “exploitation detected” in a Microsoft advisory normally implies the flaw is being exploited by cybercriminals, it appears labeled this way with CVE-2024-43491 because the rollback of fixes reintroduced vulnerabilities that were previously know to be exploited.
