[Contributed] How to: get root on a Foscam FI9831W (2017)
Note: this is a contributed post by Jens Heine <binbash@gmx.net> – please reach out to him if there any questions or comments! And a big “thank you” from me (Rink) for your contribution! This firmware modification is mainly inspired from … Continue reading
Implementing a std::function<>-like wrapper in C++, part 3: using a static storage buffer
Previously, we’ve made our version of std::move_only_function<> generic so that it can be used to store any function signature, regardless of the number of parameters or return type. The implementation we’ve ended up with is the following: This works for … Continue reading
Implementing a std::function<>-like wrapper in C++, part 2: generalizing the return type and arguments
Introduction Previously, we’ve seen a way to implement our own version of std::move_only_function<>. The implementation we ended up with is as follows: This works for any movable function, for example: Unfortunately, it is restricted to the function prototype int fn(int, … Continue reading
Implementing a std::function<>-like wrapper in C++, part 1: type erasing
Introduction Recently, a chat with a friend peeked my interested: how would you store an arbitrary function and call it, similar to std::function<>. It turned out a plain C function pointer would suffice for this specific use-case, but I got … Continue reading
Hacking into a Foscam FI9853EP camera, part 2
In my last post, I examined how to get U-Boot access and obtain the flash data from a Foscam FI9853EP camera. Whereas this data is very useful for offline analysis, I wanted to get a root shell so I can … Continue reading
Hacking into a Foscam FI9853EP camera, part 1
I have a Foscam FI9853EP, which was introduced in 2014 and has long since been obsoleted. One of the things that stands out, is that all firmware is encrypted: I was curious: what could be in the firmware that needs … Continue reading
Behind the magic of magic_enum
Recently, a coworker pointed me towards a C++17 library to convert enumeration values to strings and vice versa. The library called magic_enum (https://github.com/Neargye/magic_enum) and it indeed feels like magic. I was immediately curious: how did they pull this off? The … Continue reading
On NetWare 3.x password hashing
Way back when, I was involved in trying to obtain passwords for a Novell NetWare 3.12 server. I won’t go into details here, suffice to say that the topic has always interested me – sufficiently to return to it 30-ish … Continue reading
Reverse engineering the NetWare 386 filesystem format
I decided to take a look into the NetWare 386 filesystem, which was used in NetWare 3.x and 4.x and perhaps later versions as well. This post serves to give a high-level background on the design and layout. Tools to … Continue reading
