Siemens SCALANCE W700 Out-of-bounds Write (CVE-2023-2194)

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace data-block0 variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dmabuffer. This flaw could allow a local privileged...

Siemens SCALANCE W700 Improper Input Validation (CVE-2023-28578)

Memory corruption in Core Services while executing the command for removing a single event listener. This plugin only works with Tenable.ot. Please visit https://www.tenable.com/products/tenable-ot for more information. %NASLMINLEVEL 80900 C Tenable, Inc. include'compat.inc'; if description...

Siemens SCALANCE W700 Integer Overflow or Wraparound (CVE-2022-39842)

An issue was discovered in the Linux kernel before 5.19. In pxa3xxgcuwrite in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of sizet versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to...

Siemens SCALANCE W700 Double Free (CVE-2022-40304)

An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. This plugin only works with Tenable.ot. Please visit...

Siemens SIMATIC and SCALANCE Devices Out-of-bounds Write (CVE-2023-45863)

An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker can trigger a race condition that results in a fillkobjpath out-of-bounds write. This plugin only works with Tenable.ot. Please visit https://www.tenable.com/products/tenable-ot for more...

Siemens SIMATIC and SCALANCE Devices Race Condition (CVE-2022-39188)

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition unmapmappingrange versus munmap, a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VMPFNMAP VMAs. This plugin only works with...

Siemens SIMATIC and SCALANCE Devices Exposure of Sensitive Information to an Unauthorized Actor (CVE-2024-5535)

Calling the OpenSSL API function SSLselectnextproto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer. A buffer overread can have a range of potential consequences such as unexpected application beahviour or a crash. In particular this iss...

Siemens SIMATIC and SCALANCE Devices NULL Pointer Dereference (CVE-2023-42754)

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...

Siemens SIMATIC and SCALANCE Devices Improper Restriction of Communication Channel to Intended Endpoints (CVE-2022-2663)

An issue was found in the Linux kernel in nfconntrackirc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nfconntrackirc configured. This plugin only works with Tenable.ot. Please visit...

Siemens SCALANCE W700 Double Free (CVE-2023-29469)

An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to...

Siemens SCALANCE W700 Missing Release of Memory after Effective Lifetime (CVE-2023-1074)

A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may occur when a user starts a malicious networking service and someone connects to this service. This could allow a local user to starve resources, causing a denial of service. This plugin only...

Siemens SCALANCE W700 Externally Controlled Reference to a Resource in Another Sphere (CVE-2023-0045)

The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall.
