تتمثل المشكلة في حدوث تجاوز سعة المخزن المؤقت (buffer overflow) قائم على المكدس، مما يسمح بتنفيذ التعليمات البرمجية عن بُعد. اكتشفها كل من توبياس شارنوفسكي وفليكس بوخمان وكريستيان كوفيتش. تم عرض هذه الثغرة الأمنية في مسابقة Pwn2Own.

تسمح هذه الثغرة للمهاجمين المتواجدين على الشبكة المجاورة بالتحايل على عملية المصادقة في المنشآت المتأثرة التي تستخدم أجهزة شاحن السيارات الكهربائية من المستوى 2 WOLFBOX. يكمن الخلل في معالجة المفاتيح التشفيرية المستخدمة في اتصالات مشفرة خاصة بالشركة المصنعة، وينتج عن عدم تهيئة متغير بشكل صحيح قبل الوصول إليه. يمكن للمهاجم استغلال ذلك لتجاوز عملية المصادقة في النظام.

Name of the Vulnerable Software and Affected Versions: Trusted Firmware-M versions through 2.1.0 Description: An issue was discovered where user-provided mailbox messages contain a pointer to a list of input arguments (`in vec`) and output arguments (`out vec`) that are never validated. Each argument list contains a buffer pointer and a buffer length field. After a PSA call, the length of the output arguments behind the unchecked pointer is updated, allowing an attacker to write anywhere in the secure firmware. This can be used to take over the control flow, leading to remote code execution (RCE). Recommendations: For versions through 2.1.0, update to the latest release to mitigate risks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

This issue allows network-adjacent attackers to execute arbitrary code on affected installations. Authentication is not required to exploit this issue. The specific flaw exists within the `wlanchnllst` function, resulting from the lack of proper validation of user-supplied data, which can cause a write past the end of an allocated buffer. An attacker can leverage this to execute code in the context of root.

This issue allows network-adjacent attackers to execute arbitrary code on affected installations. Authentication is not required to exploit this issue. The specific flaw exists within the `SrvrToSmSetAutoChnlListMsg` function, resulting from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this issue to execute code in the context of root.

This issue allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-AX5500 devices. Authentication is not required to exploit this issue. The specific flaw exists within the handling of software updates, resulting from the lack of proper validation of software update packages. An attacker can leverage this issue to execute code in the context of the device.

This issue allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-AX5500 devices. Authentication is not required to exploit this issue. The specific flaw exists within the USB host driver. A crafted USB configuration descriptor can trigger an overflow of a fixed-length buffer. An attacker can leverage this issue to execute code in the context of the device.

An unauthenticated remote attacker can perform a remote code execution due to an origin validation error. The access is limited to the service user.

The issue is related to inconsistent handling of error cases in Bluetooth HCI, which may lead to a double free condition of a network buffer.

Name of the Vulnerable Software and Affected Versions: Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02) ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior ICONICS GenBroker32 version 9.5 and prior Description: A deserialization vulnerability exists, allowing remote code execution and a denial-of-service condition due to a specially crafted communication packet sent to the affected devices. This issue is related to the restoration of an untrusted data structure in memory, which can be exploited by a remote attacker to execute arbitrary code or cause a denial-of-service. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version later than 4.02C (10.95.208.31) to resolve the issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version later than 3.00A (9.50.255.02) to resolve the issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version later than 10.96 to resolve the issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version later than 9.5 to resolve the issue. As a temporary workaround, consider restricting access to the deserialization functionality until a patch is available.

The issue is related to deficiencies in the deserialization mechanism, which can be exploited by a remote attacker to cause a denial-of-service condition. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version that fixes the deserialization issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version that fixes the deserialization issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version that fixes the deserialization issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version that fixes the deserialization issue. As a temporary workaround, consider restricting access to the deserialization mechanism until a patch is available.

A buffer overflow issue is present due to an integer underflow during 6LoWPAN fragment processing in the face of truncated fragments in os/net/ipv6/sicslowpan.c. This results in accesses of unmapped memory, crashing the application. An attacker can cause a denial-of-service via a crafted 6LoWPAN frame.

An issue is present in the data section during 6LoWPAN fragment re-assembly due to forged fragment offsets in os/net/ipv6/sicslowpan.c, resulting in an out of bounds write.

The issue allows remote attackers to disclose sensitive information due to the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure. Authentication is not required to exploit this issue. This is only applicable to installations using DNP3 Data Sets.

The issue allows remote attackers to execute arbitrary code due to the lack of proper validation of user-supplied data, resulting in a type confusion condition. Authentication is not required to exploit this issue. This is only applicable to installations using DNP3 Data Sets.

An issue was discovered in the Interpeak IPCOMShell TELNET server. The undocumented shell command "prompt" sets the shell's prompt value, which is used as a format string input to printf, resulting in an information leak of memory addresses.

An issue in the Interpeak IPCOMShell TELNET server allows an attacker to forge a path containing format string modifiers when using the pwd command. This results in an information leak of memory addresses due to the lack of proper checks on the current working directory path used as an argument to printf().

An issue was discovered in the Interpeak IPCOMShell TELNET server. The main shell handler function uses the value of the environment variable `ipcom.shell.greeting` as the first argument to `printf()`, resulting in a user-controlled format string during login. This leads to an information leak of memory addresses.

The issue is related to the allocation of 60 bytes for the HTTP Authentication header in Interpeak IPWEBS on Green Hills INTEGRITY RTOS. When copying this header to parse, it does not check the size of the header, leading to a stack-based buffer overflow.
