Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU94329
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2024-37890
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when handling requests with the number of headers that exceeds the "server.maxHeadersCount" value. A remote attacker can send a specially crafted request to the application and perform a denial of service (DoS) attack.

2) Server-Side Request Forgery (SSRF)
EUVDB-ID: #VU95816
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2024-29415
CWE-ID:
CWE-918 - Server-Side Request Forgery (SSRF)
Exploit availability: Yes
DescriptionThe disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input within the isPublic() function when handling certain IP addresses, such as 127.1, 01200034567, 012.1.2.3, 000:0:0000::01, and ::fFFf:127.0.0.1. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
Note, the vulnerability exists due to incomplete fix for #VU86944 (CVE-2023-42282).
