Kyocera Device Manager before 3.1.1213.0 allows NTLM credential exposure during UNC path authentication via a crafted change from a local path to a UNC path. It allows administrators to configure the backup location of the database used by the application. Attempting to change this location to a UNC path via the GUI is rejected due to the use of a \ (backslash) character, which is supposed to be disallowed in a pathname. Intercepting and modifying this request via a proxy, or sending the request directly to the application endpoint, allows UNC paths to be set for the backup location. Once such a location is set, Kyocera Device Manager attempts to confirm access and will try to authenticate to the UNC path; depending on the configuration of the environment, this may authenticate to the UNC with Windows NTLM hashes. This could allow NTLM credential relaying or cracking attacks.

Kyocera TASKalfa 4053ci printers through 2VG_S000.002.561 allow identification of valid user accounts via username enumeration because they lead to a "nicht einloggen" error rather than a falsch error.

Kyocera TASKalfa 4053ci printers through 2VG_S000.002.561 allow a denial of service (service outage) via /wlmdeu%2f%2e%2e%2f%2e%2e followed by a directory reference such as %2fetc%00index.htm to try to read the /etc directory.

Kyocera TASKalfa 4053ci printers through 2VG_S000.002.561 allow /wlmdeu%2f%2e%2e%2f%2e%2e directory traversal to read arbitrary files on the filesystem, even files that require root privileges. NOTE: this issue exists because of an incomplete fix for CVE-2020-23575.

KYOCERA Mobile Print' v3.2.0.230119 and earlier, 'UTAX/TA MobilePrint' v3.2.0.230119 and earlier, and 'Olivetti Mobile Print' v3.2.0.230119 and earlier are vulnerable to improper intent handling. When a malicious app is installed on the victim user's Android device, the app may send an intent and direct the affected app to download malicious files or apps to the device without notification.

Affected products/versions are as follows: TASKalfa 7550ci/6550ci, TASKalfa 5550ci/4550ci/3550ci/3050ci, TASKalfa 255c/205c, TASKalfa 256ci/206ci, ECOSYS M6526cdn/M6526cidn, FS-C2126MFP/C2126MFP+/C2026MFP/C2026MFP+, TASKalfa 8000i/6500i, TASKalfa 5500i/4500i/3500i, TASKalfa 305/255, TASKalfa 306i/256i, LS-3140MFP/3140MFP+/3640MFP, ECOSYS M2535dn, LS-1135MFP/1035MFP, LS-C8650DN/C8600DN, ECOSYS P6026cdn, FS-C5250DN, LS-4300DN/4200DN/2100DN, ECOSYS P4040dn, ECOSYS P2135dn, and FS-1370DN.

Kyocera multifunction printers running vulnerable versions of Net View unintentionally expose sensitive user information, including usernames and passwords, through an insufficiently protected address book export function.

A directory traversal vulnerability exists in Kyocera Printer d-COPIA253MF plus. Successful exploitation of this vulnerability could allow an attacker to retrieve or view arbitrary files from the affected server.
