GHSA-7RW7-XM59-WMR8

Vulnerability from github – Published: 2022-05-24 17:45 – Updated: 2022-05-24 17:45
VLAI
Details

Multiple vulnerabilities in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to cause the web UI software to become unresponsive and consume vty line instances, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient error handling in the web UI. An attacker could exploit these vulnerabilities by sending crafted HTTP packets to an affected device. A successful exploit could allow the attacker to cause the web UI software to become unresponsive and consume all available vty lines, preventing new session establishment and resulting in a DoS condition. Manual intervention would be required to regain web UI and vty session functionality. Note: These vulnerabilities do not affect the console connection.

GHSA-7VM6-QWH5-9X44

Vulnerability from github – Published: 2024-11-04 23:22 – Updated: 2024-11-05 18:35
VLAI
Summary
loona-hpack Panic Vulnerability
Details

Summary

loona-hpack suffers from the same vulnerability as the original hpack as documented in https://github.com/mlalic/hpack-rs/issues/11

Details

The original includes a very nice description of the problem, as well as an easy-enough fix for it.

PoC

The original example pretty much still applies:

use loona_hpack::Decoder;

pub fn main() {
    let input = &[0x3f];
    let mut decoder = Decoder::new();
    let _ = decoder.decode(input);
}

Impact

From the original: All users who try to decode untrusted input using the Decoder are vulnerable to this exploit. A patched version of the crate is available on [crates.io](https://crates.io/crates/hpack-patched) under the name hpack-patched. See [Cargo's documentation on overriding dependencies](https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html) for more information.

Details

Python Facebook Thrift servers would not error upon receiving messages with containers of fields of unknown type. As a result, malicious clients could send short messages which would take a long time for the server to parse, potentially leading to denial of service. This issue affects Facebook Thrift prior to v2019.02.18.00.

A vulnerability in the processing of TCP MD5 authentication in Juniper Networks Junos OS Evolved may allow a BGP or LDP session configured with MD5 authentication to succeed, even if the peer does not have TCP MD5 authentication enabled. This could lead to untrusted or unauthorized sessions being established, resulting in an impact on confidentiality or stability of the network. This issue affects Juniper Networks Junos OS Evolved: All versions prior to 20.3R2-S1-EVO; 20.4 versions prior to 20.4R2-EVO; 21.1 versions prior to 21.1R2-EVO. Juniper Networks Junos OS is not affected by this issue.
