Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-71943
HighEPSS 87%

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the setDevNet function. The vulnerability is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

CVE-2026-71942
High

Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the mail_mailalert function. The vulnerability is caused by concatenating multiple smtpReceiver email addresses into a fixed-size buffer without checking the remaining buffer size. A remote attacker can trigger this vulnerability via crafted input, causing a denial of service or potentially executing arbitrary commands. Exploitation requires valid administrative credentials for the device's web management interface.

CVE-2026-71941
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the diag_logmail function. The issue is caused by concatenating multiple smtpReceiver email addresses into a fixed-size buffer without checking remaining space. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71940
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the acl_general_setup Edit ACE function. The issue is caused by copying the name field into a fixed-size buffer without length validation. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71939
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the acl_general_setup Add ACE function. The issue is caused by copying the name field into a fixed-size buffer without length validation. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71938
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the switch_lan_gvrp function. The issue is caused by unsafe copying of the portList field into an undersized buffer. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71937
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the poe_schedule_profile function. The issue is caused by repeated concatenation of start_date, start_time, duration_time, how_often, weekdays, monthly_date, and cycle_duration fields into small fixed-size buffers without proper length checks. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71936
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the sysreboot function. The issue is caused by unsafe concatenation of split valueN data into a fixed-size buffer. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71935
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the webBackupAction function. The issue is caused by repeated string concatenation of pathN, valueN, key, and option fields into fixed-size stack buffers without total length checks. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71934
High

Multiple DrayTek VigorSwitch models have a buffer overflow vulnerability in the pingtrace function. The issue is caused by missing length checks when the host, count, and interval fields are concatenated into a fixed-size buffer. A remote attacker can trigger this via crafted input, causing denial of service or potential arbitrary command execution. Valid administrative credentials for the web management interface are required.

CVE-2026-71933
Critical

Multiple DrayTek VigorSwitch models contain unauthorized operation vulnerabilities in multiple syslog functions. The vulnerability is caused by missing authorization checks. A remote attacker can trigger these vulnerabilities via crafted requests to modify configuration, restart services, save startup configuration, or clear logs.

CVE-2026-71932
MediumEPSS 50%

Multiple DrayTek VigorSwitch models contain a directory traversal vulnerability in the getSyslogFile function due to insufficient validation of the option field. A remote attacker can access arbitrary files on the device via crafted input. Exploitation requires valid administrative credentials for the web management interface.

CVE-2026-71931
HighEPSS 83%

Multiple DrayTek VigorSwitch models have a command injection vulnerability in the tftp_upgrade function. The issue is caused by insufficient filtering before the filename field is concatenated into a command. A remote attacker can trigger this via crafted input to execute arbitrary commands with root privileges. Valid administrative credentials for the web management interface are required.

CVE-2026-71930
HighEPSS 87%

Multiple DrayTek VigorSwitch models have a command injection vulnerability in the setTime function. The issue is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can trigger this via crafted input to execute arbitrary commands with root privileges. Valid administrative credentials for the web management interface are required.

CVE-2026-71929
HighEPSS 87%

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the setDevProto function. The issue is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can exploit this to execute arbitrary commands with root privileges, but requires valid administrative credentials.

CVE-2026-71928
HighEPSS 75%

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the fdftDevice function. The issue is caused by insufficient filtering of the username and password fields before command execution.
