Original advisory text
TeamDavid: Buffer Overflow in file names of file upload functionalities
Tobit Laboratories AG TeamDavid's Webbox application implements various file upload functionalities that are
vulnerable to a buffer overflow condition. By specifying an excessively
long filename in a file upload request, an unauthenticated attacker can
trigger a crash of the server, resulting in a denial of service.
Depending on the stack state or if a stack canary can be disclosed
through another vulnerability, this buffer overflow could potentially be
exploited for remote code execution, leading to full compromise of the
server. This issue affects TeamDavid through Rollout 524.
