Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper access control (CVE-ID: CVE-2021-39226)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions to database snapshots. Remote unauthenticated and authenticated users are able to view the snapshot with the lowest database key by accessing the literal paths: /dashboard/snapshot/:key, or /api/snapshots/:key. If the snapshot "public_mode" configuration setting is set to true (vs default of false), unauthenticated users are able to delete the snapshot with the lowest database key by accessing the literal path: /api/snapshots-delete/:deleteKey.
Regardless of the snapshot "public_mode" setting, authenticated users are able to delete the snapshot with the lowest database key by accessing the literal paths: /api/snapshots/:key, or /api/snapshots-delete/:deleteKey. The combination of deletion and viewing enables a complete walk through all snapshot data while resulting in complete snapshot data loss.
2) OS Command Injection (CVE-ID: CVE-2022-26945)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Input validation error (CVE-ID: CVE-2022-30321)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an unspecified error. A remote attacker can perform a denial of service (DoS) attack.
4) Input validation error (CVE-ID: CVE-2022-30322)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an unspecified error. A remote attacker can perform a denial of service (DoS) attack.
5) Input validation error (CVE-ID: CVE-2022-30323)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an unspecified error. A remote attacker can perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2022-30631)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in Reader.Read method when handling an archive that contains a large number of concatenated 0-length compressed files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
7) Information disclosure (CVE-ID: CVE-2022-0494)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in the scsi_ioctl() function in drivers/scsi/scsi_ioctl.c in the Linux kernel. A local user with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) can gain unauthorized access to sensitive information on the system.
8) Information disclosure (CVE-ID: CVE-2022-1353)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the pfkey_register function in net/key/af_key.c in the Linux kernel. A local user can gain unauthorized access to kernel memory, leading to a system crash or a leak of internal kernel information.
9) Use-after-free (CVE-ID: CVE-2022-2526)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the on_stream_io() and dns_stream_complete() functions in resolved-dns-stream.c, which do not increment the reference counting for the DnsStream object. A remote attacker can send to the system specially crafted DNS responses, trigger a use-after-free error and perform a denial of service (DoS) attack.
10) Path traversal (CVE-ID: CVE-2022-29154)
The vulnerability allows a remote server to perform directory traversal attacks.
The vulnerability exists due to input validation error within the rsync client when processing file names. A remote malicious server overwrite arbitrary files in the rsync client target directory and subdirectories on the connected peer.
