Azure RTOS USBX Remote Code Execution Vulnerability
Summary
Azure RTOS USBX is a USB host, device, and on-the-go (OTG) embedded stack, that is fully integrated with Azure RTOS ThreadX. An attacker can cause remote code execution due to expired pointer dereference vulnerabilities in Azure RTOS USBX. The affected components include functions/processes in host stack and host classes, related to device linked classes, GSER and HID in RTOS v6.2.1 and below. The fixes have been included in USBX release 6.3.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Title
Improper Check or Handling of Exceptional Conditions in apollo-router
Summary
The Apollo Router is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation. Affected versions are subject to a Denial-of-Service (DoS) type vulnerability which causes the Router to panic and terminate when a multi-part response is sent. When users send queries to the router that uses the `@defer` or Subscriptions, the Router will panic. To be vulnerable, users of Router must have a coprocessor with `coprocessor.supergraph.response` configured in their `router.yaml` and also to support either `@defer` or Subscriptions. Apollo Router version 1.33.0 has a fix for this vulnerability which was introduced in PR #4014. Users are advised to upgrade. Users unable to upgrade should avoid using the coprocessor supergraph response or disable defer and subscriptions support and continue to use the coprocessor supergraph response.

Title
Junos OS: SRX Series and MX Series: SIP ALG doesn't drop specifically malformed retransmitted SIP packets
Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated network-based attacker to cause an integrity impact in connected networks.
If the SIP ALG is configured and a device receives a specifically malformed SIP packet, the device prevents this packet from being forwarded, but any subsequently received retransmissions of the same packet are forwarded as if they were valid.
This issue affects Juniper Networks Junos OS on SRX Series and MX Series:
* 20.4 versions prior to 20.4R3-S5;
* 21.1 versions prior to 21.1R3-S4;
* 21.2 versions prior to 21.2R3-S4;
* 21.3 versions prior to 21.3R3-S3;
* 21.4 versions prior to 21.4R3-S2;
* 22.1 versions prior to 22.1R2-S2, 22.1R3;
* 22.2 versions prior to 22.2R2-S1, 22.2R3;
* 22.3 versions prior to 22.3R1-S2, 22.3R2.
This issue doesn't not affected releases prior to 20.4R1.

Title
Junos OS Evolved: PTX10003 Series: Packets which are not destined to the router can reach the RE
Summary
An Improper Check for Unusual or Exceptional Conditions in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS Evolved on PTX10003 Series allows an unauthenticated adjacent attacker to cause an impact to the integrity of the system.
When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the RE. This issue is a prerequisite for CVE-2023-44195.
This issue affects Juniper Networks Junos OS Evolved:
* All versions prior to 20.4R3-S8-EVO;
* 21.1-EVO version 21.1R1-EVO and later;
* 21.2-EVO versions prior to 21.2R3-S6-EVO;
* 21.3-EVO version 21.3R1-EVO and later;
* 21.4-EVO versions prior to 21.4R3-S3-EVO;
* 22.1-EVO versions prior to 22.1R3-S4-EVO;
* 22.2-EVO versions prior to 22.2R3-S3-EVO;
* 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-EVO;
* 22.4-EVO versions prior to 22.4R2-EVO.

Mitigation MIT-3
Requirements
Strategy: Language Selection
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Choose languages with features such as exception handling that force the programmer to anticipate unusual conditions that may generate exceptions. Custom exceptions may need to be developed to handle unusual business-logic conditions. Be careful not to pass sensitive exceptions back to the user (CWE-209, CWE-248).
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is expected.
Mitigation
Implementation
If using exception handling, catch and throw specific exceptions instead of overly-general exceptions (CWE-396, CWE-397). Catch and handle exceptions as locally as possible so that exceptions do not propagate too far up the call stack (CWE-705). Avoid unchecked or uncaught exceptions where feasible (CWE-248).
Mitigation MIT-39
Implementation
- Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
- If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
- Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
- Exposing additional information to a potential attacker in the context of an exceptional condition can help the attacker determine what attack vectors are most likely to succeed beyond DoS.
Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mitigation MIT-38
Architecture and Design
Implementation
If the program must fail, ensure that it fails gracefully (fails closed). There may be a temptation to simply let the program fail poorly in cases such as low memory conditions, but an attacker may be able to assert control before the software has fully exited. Alternately, an uncontrolled failure could cause cascading problems with other downstream components; for example, the program could send a signal to a downstream process so the process immediately knows that a problem has occurred and has a better chance of recovery.
Mitigation
Architecture and Design
Use system limits, which should help to prevent resource exhaustion. However, the product should still handle low resource conditions since they may still occur.
No CAPEC attack patterns related to this CWE.
