Here's a look behind the curtain at the less glamorous side of vuln research, discussing (in mostly laypersons' terms) how we tried in vain to turn a memory corruption bug into full RCE. https://bishopfox.com/blog/a-crash-not-a-shell-solarwinds-serev-u-cve-2026-2831817 Jun 2026 10:04 +0000at://did:plc:3hicryvxip2c2z4eb7wtpyvm/app.bsky.feed.post/3moi2sljols2khttps://bsky.app/profile/br4inde4d.bsky.social/post/3mnmfyokjuc2bHere we GOOOOOO...! Successfully reproduced a full root unauthenticated RCE chain against UniFi OS Server 5.0.6 – with devastating impacts depending on what devices it manages.

This week I published some research into a perfect 10 arbitrary file read affecting Ubiquiti UniFi controller software. I suspect we’ll have more to say about UniFi in the near future… https://bishopfox.com/blog/looting-unifi-controllers-detecting-and-weaponizing-cve-2026-2255703 Jun 2026 10:02 +0000at://did:plc:3hicryvxip2c2z4eb7wtpyvm/app.bsky.feed.post/3mneu5fceks2phttps://bsky.app/profile/br4inde4d.bsky.social/post/3mmvsijbmb22kDropped some new research on the blog this week - this time we’re pulling apart a PAN-OS JWT signature bypass.

We withheld exploit details because the root cause has not been fully mitigated. Patch now if you haven't already, disable your captive portal to reduce the likelihood of exploitation, and stay tuned for new vulns to be disclosed soon! https://bishopfox.com/blog/arista-nextgen-firewall-xss-to-rce-chain05 Dec 2025 09:17 +0000at://did:plc:3hicryvxip2c2z4eb7wtpyvm/app.bsky.feed.post/3m7a5p5yaus2bhttps://bsky.app/profile/br4inde4d.bsky.social/post/3m75votckms2kMy team confirmed that recently disclosed Arista NGFW vulnerabilities are fully exploitable! RCE is possible with victim interaction.

We developed a semi-automated analysis workflow and benchmarked four high-impact vulns using a few different Claude models.
