Vulnerabilities (Page 40)

There is a bit of a race condition in some areas of kernel code a file that has been closed by userspace will still be accessed by the kernel.

Exactly as the title puts it, cross-site scripting through content injected from the X-Forwarded-Host header. Its interesting that this one was paid out as without some other issue like cache poisoning it would be impossible as far I am aware to exploit this as you cannot control the headers of a random user’s requests.

An inability to decode the character in a user’s post, leading to HTTP 500 response.

Just send an email pretending to be part of another report and the system will make you part of it.Its really that simple, sending an email using your the email associated with your Researcher portal account with the subject VULN-<report number>will get that email added to the report and be copied on future updates…

Little Snitch might block connections to some IPs, but only if they send data. Just opening the connection but not sending data is a fun way to get around the blacklist, and while significantly slower, one can still exfiltrate information using only a data-less connection.

This is almost an intended feature, basically if an attacker can craft a their own State cookie, they can trick the StateFilter into reading the forwardPath and forwarding their request to another servlet directly. The interesting side-effect here is that the redirect will bypass any other filters left in the chain and go directly to the other servlet.

Two vulnerabilities in Zoom, a buffer overflow that affected Multi-Media Routers (MMR) servers and client, and an infoleak that only affected MMR servers. Both issues were found in various load_from() methods for serialization classes used in Real-time Transport Protocol (RTP) for audio/video content.

Use-after-free in the ipc_port subsystem of XNU, specifically the ipc_port_copy_send() function.This function would try to copy and send data on an IPC port, and attempts to account for a bunch of edge-cases on the state of the port…

Kernel bug in KCodes’ NetUSB kernel module, which is used by various network device vendors for routers and such.The vulnerability is in the dispatchNormalEPMsgOut() handler for an unlabelled command of 0x805f…

Integer underflow in fs_context.c’s legacy_parse_param() function which was introduced in v5.1.When bounds checking the provided options length, they compare it with system page size - 2 - context data size…
