EUVDB-ID: #VU23672
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-16555
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a user-supplied regular expression is processed in a way that is not interruptible. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

EUVDB-ID: #VU23670
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-16553
CWE-ID:
CWE-352 - Cross-Site Request Forgery (CSRF)
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website, such as supply a computationally expensive regular expression that will hang the request handling thread.
MitigationInstall updates from vendor's website.
