2017-030-Vulnerability OSINT, derbycon CTF walkthrough, and bsides Wellington!

This week, we discuss the lack of information and where you might find more information about certain vulnerabilities. Seems like many companies fail to give out necessary and actionable information without paying an arm and a leg.

We also go over our DerbyCon CTF walkthrough, and discuss the steps to solve it.

Vuln OSINT

 

Sites have information like Spokeo…

Breadcrumbs

 

Take Java for example (CVE-2017-10102): info is sparse

Other sites have more

https://tools.cisco.com/security/center/viewAlert.x?alertId=54521 - worse than Oracle’s site (impressive crappery)

Some are better: RHEL is fairly decent

https://access.redhat.com/errata/RHSA-2017:2424

Ubuntu has some different tidbits

https://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-10102.html

Arch has info

https://security.archlinux.org/CVE-2017-10102

Point is, just because you use a specific OS, don’t limit yourself… other OSes may contain more technical info. Some maintainers like to dig, like you.

 

https://vuldb.com/ - gives value of finding such a PoC for a vuln (5-25K USD for 2017-10102)
