A vulnerability was found in FreeBSD (Operating System) (the affected version is unknown). It has been rated as critical. This issue affects the function copy_file_range system
of the component Capsicum. The manipulation with an unknown input leads to a dropped privileges vulnerability. Using CWE to declare the problem leads to CWE-273. The product attempts to drop privileges but does not check or incorrectly checks to see if the drop succeeded. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
Before correction, the copy_file_range system call checked only for the CAP_READ and CAP_WRITE capabilities on the input and output file descriptors, respectively. Using an offset is logically equivalent to seeking, and the system call must additionally require the CAP_SEEK capability. This incorrect privilege check enabled sandboxed processes with only read or write but no seek capability on a file descriptor to read data from or write data to an arbitrary location within the file corresponding to that file descriptor.
The weakness was disclosed 10/04/2023. The advisory is shared at security.FreeBSD.org. The identification of this vulnerability is CVE-2023-5369 since 10/03/2023. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.
