CVE-2023-3247
CVSS v3.1
4.3
Medium
| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
PHP versions 8.0.* through 8.0.28
PHP versions 8.1.* through 8.1.19
PHP versions 8.2.* through 8.2.6
Description
The issue is related to the use of a random value generator with a narrower range of values than it should have when using SOAP HTTP Digest Authentication. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce.
Recommendations
For PHP versions 8.0.* through 8.0.28, update to version 8.0.29 or later.
For PHP versions 8.1.* through 8.1.19, update to version 8.1.20 or later.
For PHP versions 8.2.* through 8.2.6, update to version 8.2.7 or later.
As a temporary workaround, consider disabling the SOAP HTTP Digest Authentication until a patch is available.
Fix
Use of Insufficiently Random Values
Unchecked Return Value
