GHSA-788R-RF8C-VGJ3

Vulnerability from github – Published: 2022-05-13 01:31 – Updated: 2022-05-13 01:31
VLAI
Details

A vulnerability in the DHCPv6 input packet processor of Cisco Prime Network Registrar could allow an unauthenticated, remote attacker to restart the server and cause a denial of service (DoS) condition on the affected system. The vulnerability is due to incomplete user-supplied input validation when a custom extension attempts to change a DHCPv6 packet received by the application. An attacker could exploit this vulnerability by sending malformed DHCPv6 packets to the application. An exploit could allow the attacker to trigger a restart of the service which, if exploited repeatedly, might lead to a DoS condition. This vulnerability can only be exploited if the administrator of the server has previously installed custom extensions that attempt to modify the packet details before the packet has been processed. Note: Although the CVSS score matches a High SIR, this has been lowered to Medium because this condition will only affect an application that has customer-developed extensions that will attempt to modify packet parameters before the packet has been completely sanitized. If packet modification in a custom extension happens after the packet has been sanitized, the application will not be affected by this vulnerability. Software versions prior to 8.3(7) and 9.1(2) are affected.

Summary
@misskey-dev/summaly Redirect Filter Bypass
Details

Summary

A logic error in the main summaly function causes the allowRedirects option to never be passed to any plugins, and as a result, isn't enforced.

Details

In the main summaly function, a new scrapingOptions object is created and passed to either the matched plugin, if any, or the default summarize function. The issue here is that the new scrapingOptions object is not provided the allowRedirects property of opts.

PoC

  • Publish a post containing a link to any URL that redirects on Misskey.
  • A preview will be generated for the target of the redirect, despite Misskey passing allowRedirects: false.

Impact

Misskey will follow redirects, despite explicitly requesting not to.

Vulnerability from github – Published: 2022-01-20 00:01 – Updated: 2022-02-02 00:02
VLAI
Details

An Improper Initialization vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker who sends specific packets in certain orders and at specific timings to force OSPFv3 to unexpectedly enter graceful-restart (GR helper mode) even though there is not any Grace-LSA received in OSPFv3 causing a Denial of Service (DoS). Unexpectedly entering GR helper mode might cause the OSPFv3 neighbor adjacency formed on this interface to be stuck in the "INIT" state which can be observed by issuing the following command: user@device> show ospf3 neighbor ID Interface State xx.xx.xx.xx ae100.0 Init <<<<<<<<<< An indicator of compromise can be seen in log files when traceoptions for OSPFv3 are enabled before the issue occurs. These logfile messages are as follows: OSPF restart signaling: Received hello with LR bit set from nbr ip=xx::xx id=xx.xx.xx.xx. Set oob-resync capabilty 1. OSPF Restart Signaling: Start helper mode for nbr ip xx::xx id xx.xx.xx.xx OSPF restart signaling: abort helper mode for nbr ip=xx::xx id=xx.xx.xx.xx OSPF neighbor xx::xx (realm ipv6-unicast area xx.xx.xx.xx) state changed from Full to Init due to 1WayRcvd (event reason: neighbor is in one-way mode) (nbr helped: 0) This issue affects: Juniper Networks Junos OS. 15.1 versions prior to 15.1R7-S11; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S7, 19.2R3-S4; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S1; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R2-S2, 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2.

Vulnerability from github – Published: 2022-05-24 17:48 – Updated: 2022-05-24 17:48
VLAI
Details

On Juniper Networks Junos OS Evolved devices, receipt of a specific IPv6 packet may cause an established IPv6 BGP session to terminate, creating a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue does not affect IPv4 BGP sessions. This issue affects IBGP or EBGP peer sessions with IPv6. This issue affects: Juniper Networks Junos OS Evolved: 19.4 versions prior to 19.4R2-S3-EVO; 20.1 versions prior to 20.1R2-S3-EVO; 20.2 versions prior to 20.2R2-S1-EVO; 20.3 versions prior to 20.3R2-EVO. This issue does not affect Juniper Networks Junos OS releases.

GHSA-7JMP-V8MH-4F8R

Vulnerability from github – Published: 2022-05-24 19:15 – Updated: 2022-05-24 19:15
VLAI
Details

A vulnerability in the Protection Against Distributed Denial of Service Attacks feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct denial of service (DoS) attacks to or through the affected device. This vulnerability is due to incorrect programming of the half-opened connections limit, TCP SYN flood limit, or TCP SYN cookie features when the features are configured in vulnerable releases of Cisco IOS XE Software. An attacker could exploit this vulnerability by attempting to flood traffic to or through the affected device. A successful exploit could allow the attacker to initiate a DoS attack to or through an affected device.

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.
  • For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable's type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.

Mitigation
Implementation

Pay close attention to complex conditionals that affect initialization, since some conditions might not perform the initialization.

Mitigation
Implementation

Avoid race conditions (CWE-362) during initialization routines.

Mitigation
Build and Compilation

Run or compile your product with settings that generate warnings about uninitialized variables or data.

CAPEC-26: Leveraging Race Conditions

The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.

CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions

This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
