This weekly blog post is from via our unique intelligence collection pipelines. We are your eyes and ears online, including the Dark Web.
There are thousands of vulnerability discussions each week. SOS Intelligence gathers a list of the most discussed Common Vulnerabilities and Exposures (CVE) online for the previous week.
We make every effort to ensure the accuracy of the data presented. As this is an automated process some errors may creep in.

1. CVE-2023-38545
An improper certificate validation vulnerability exists in curl
https://nvd.nist.gov/vuln/detail/CVE-2023-38545
2. CVE-2023-4911
A buffer overflow was discovered in the GNU C Library’s dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.

3. CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

4. CVE-2019-9511
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim’s traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

5. CVE-2022-40684
An authentication bypass using an alternate path or channel [CWE-288] in Fortinet FortiOS version 7.2.0 through 7.2.1 and 7.0.0 through 7.0.6, FortiProxy version 7.2.0 and version 7.0.0 through 7.0.6 and FortiSwitchManager version 7.2.0 and 7.0.0 allows an unauthenticated atttacker to perform operations on the administrative interface via specially crafted HTTP or HTTPS requests.
