No. We are not aware of malware exploiting this vulnerability.

2) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU80472

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-20898

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to Git Providers get the same cache directory base name and can read from the wrong environment. A local user can gain access to sensitive information or corrupt data.

Mitigation

Update the affected packages.
app-admin/salt to version: 3006.6

Vulnerable software versions

Gentoo Linux: All versions

app-admin/salt: before 3006.6

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) UNIX symbolic link following

EUVDB-ID: #VU82944

Risk: Low

CVSSv4.0: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear]

CVE-ID: CVE-2023-34049

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a symlink following issue in Salt-SSH pre-flight option. A local user can create a specially crafted symbolic link to an empty file on the system, wait for the salt to create the file for further execution, update the symbolic link and point it to another file that is under attacker's control and execute the file with root privileges.

Mitigation

Update the affected packages.
