CWE-ID: -

CVSSv4: []


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

Integer Overflow or Wraparound vulnerability in Cesanta Mongoose Web Server v7.14 allows an attacker to send an unexpected TLS packet and produce a segmentation fault on the application.


6) Missing Authentication for Critical Function (CVE-ID: CVE-2026-62645)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to improper authentication. A remote attacker can bypass the authentication and gain unauthorized access to the device.


7) Insufficient Entropy (CVE-ID: CVE-2026-62646)

CWE-ID: CWE-331 - Insufficient Entropy

CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the session identifier is generated using an algorithm with insufficient randomness. A remote attacker can derive valid session identifiers and bypass authentication.


8) Input validation error (CVE-ID: CVE-2026-62647)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the use of an improperly initialized random number generator for generating security-relevant values. A remote attacker can gain unauthorized access to the target device.


9) Out-of-bounds write (CVE-ID: CVE-2026-62648)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger an out-of-bounds write and perform a denial of service (DoS) attack on the target system.


10) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-62649)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the web server does not properly limit or manage system resources when processing a high volume of concurrent HTTP requests. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


11) Authentication bypass using an alternate path or channel (CVE-ID: CVE-2026-62650)

CWE-ID: CWE-288 - Authentication Bypass Using an Alternate Path or Channel

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to server-side authorization checks in the web-based management interface are not properly enforced. A remote user can bypass authentication process and gain elevated privileges on the system.


12) Insertion of Sensitive Information Into Debugging Code (CVE-ID: CVE-2026-62652)

CWE-ID: CWE-215 - Insertion of Sensitive Information Into Debugging Code

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the device firmware contains binaries from which debugging symbols have not been removed. A remote attacker can gain unauthorized access to sensitive information on the system.


13) Out-of-bounds write (CVE-ID: CVE-2026-62653)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. An attacker with physical access can trigger an out-of-bounds write and execute arbitrary code on the target system.


14) Download of code without integrity check (CVE-ID: CVE-2026-62654)

CWE-ID: CWE-494 - Download of Code Without Integrity Check

CVSSv4: 7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
