CVE-2022-23046

The original discovery and manual PoC is from Fluidattacks:

PhpIPAM v1.4.4 allows an authenticated admin user to inject SQL sentences in the "subnet" parameter while searching a subnet via app/admin/routing/edit-bgp-mapping-search.php.

This PoC executes some easy SQLi to fetch info like:

• Basic Server Info
• SMTP Settings
• Other authentication method like AD/LDAP/Radius
• PHPIpam Users and hashes
• MySQL db Users
• Other schemas availables

Some of them are accessible through the backend but I added here just as an easy way to fetch all the information in a single query. Feel free to add/remove your own payloads

For more advanced stuff, create your own payloads (in res.payloads), use burpsuite or use sqlmap.

Additional info

I've been testing this PoC in different phpipam versions 1.4.3, 1.4.4 and 1.5 which worked fine (not only < 1.4.5). Checking at the phpipam github project I saw that the commit 4b764b9cb236d1a4a06fc8ad9a93b306b3f5c04d also affected version 1.5

Usefull file: https://github.com/phpipam/phpipam/blob/master/misc/CHANGELOG

Check if CHANGELOG is accessible and has the comment about this fix, otherwise the phpipam server may be vulnerable
