Vulnerabilities in this advisory
- CVE-2024-42384 — CVE-2024-42384 · CWE-190
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.
- CVE-2024-42385 — CVE-2024-42385 · CWE-140
Improper Neutralization of Delimiters vulnerability in Cesanta Mongoose Web Server v7.14 allows to trigger an out-of-bound memory write if the PEM certificate contains unexpected characters.
- CVE-2024-42386 — CVE-2024-42386 · CWE-823
Use of Out-of-range Pointer Offset 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.
- CVE-2024-42391 — CVE-2024-42391 · CWE-823
Use of Out-of-range Pointer Offset vulnerability in Cesanta Mongoose Web Server v7.14 allows an attacker to send an unexpected TLS packet and force the application to read unintended heap memory space.
- CVE-2024-42392 — CVE-2024-42392 · CWE-140
Improper Neutralization of Delimiters vulnerability in Cesanta Mongoose Web Server v7.14 allows to trigger an infinite loop bug if the input string contains unexpected characters.
- CVE-2026-62645 — CVE-2026-62645 · CWE-306
Information is exposed through the web interface that can be used to calculate the current and past session ID numbers. This could allow an attacker to bypass the authentication and gain unauthorized access to the device.
- CVE-2026-62646 — CVE-2026-62646 · CWE-331
A session identifier is generated using an algorithm with insufficient randomness, resulting in a token with low entropy that can be predicted or brute-forced within a feasible number of attempts. This could allow an unauthenticated remote attacker to derive valid session identifiers and bypass authentication.
- CVE-2026-62647 — CVE-2026-62647 · CWE-20
A random number generator is used to generate security-relevant values (such as session identifiers used for authentication purposes) that is not initialized with a True Random Number Generator (TRNG), resulting in a predictable sequence of generated values. This could allow an unauthenticated remote attacker to more easily predict the generated values and impersonate a legitimate authenticated user, potentially gaining unauthorized access to the device.
- CVE-2026-62648 — CVE-2026-62648 · CWE-787
The length of the URL component contained in pre-authenticated HTTP messages is not properly validated before appending additional data to it, resulting in an out-of-bounds write condition in memory. This could allow an unauthenticated remote attacker to crash the affected device, causing a reboot and resulting in a denial-of-service condition.
- CVE-2026-62649 — CVE-2026-62649 · CWE-770
The web server does not properly limit or manage system resources when processing a high volume of concurrent HTTP requests. This could allow an unauthenticated remote attacker to cause the entire device to crash and reboot, resulting in a denial-of-service condition.
- CVE-2026-62650 — CVE-2026-62650 · CWE-288
Server-side authorization checks in the web-based management interface are not properly enforced, allowing role-based access control (RBAC) restrictions to be bypassed through manipulation of request data. This could allow an authenticated, low-privileged remote attacker to escalate privileges to an administrative level.
- CVE-2026-62652 — CVE-2026-62652 · CWE-215
The device firmware contains binaries from which debugging symbols have not been removed. This could allow an unauthenticated attacker with access to the publicly available firmware update files to more easily reverse engineer the device's firmware, facilitating the identification of further vulnerabilities.
- CVE-2026-62653 — CVE-2026-62653 · CWE-787
The input received over a proprietary communication protocol that is exposed when the device is placed into a special firmware-update mode is not properly validated, resulting in a memory corruption condition. This could allow an unauthenticated attacker with physical access to the device to cause a crash and potentially execute arbitrary code on the device.
- CVE-2026-62654 — CVE-2026-62654 · CWE-494
A special maintenance mode can be activated via a physical key sequence during device boot, in which the device downloads and executes program code from a network server without verifying its authenticity or integrity. This could allow an attacker with physical access to the device to upload and execute arbitrary, unsigned code.
