The AFS3 file server exploit is a type of remote code execution (RCE) vulnerability that affects the AFS3 file server, allowing an attacker to execute arbitrary code on the server. This vulnerability is caused by a buffer overflow in the AFS3 file server's handling of certain types of packets, which can be exploited by an attacker to inject malicious code into the server.
: An attacker could trigger the use of uninitialized memory in the OpenAFS fileserver , potentially leading to arbitrary code execution with the privileges of the fileserver process. afs3-fileserver exploit
Unexpected restarts of the fileserver or volserver processes accompanied by core dumps. The AFS3 file server exploit is a type
afs3-callback used by the server to inform clients of file modifications. Unexpected restarts of the fileserver or volserver processes
: AFS-3 provides two data fetch RPC variants: FS.FetchData and FS.FetchData64 . If a client attempted to process a large file read where the file offset crossed the 2GB to 4GB boundary, signed 32-bit variables within the legacy FS.FetchData structure would overflow due to signedness bit interpretation.
