Foxed Up: How phpFox Got Outfoxed by a PHP Vulnerability

Popular social network software, phpFox, had a brush with an embarrassing PHP Object Injection Vulnerability due to unsanitized user input. The sly fox learnt a hard lesson on cybersecurity after being the hunted rather than the hunter.

Hot Take:

Well, well, well, it seems like the Fox got outfoxed! The popular social network software, phpFox was caught with its pants down revealing a rather unsightly PHP Object Injection Vulnerability. Unsanitized user input – it’s like inviting a vampire into your house, and then wondering why you’re feeling a bit anemic! C’mon phpFox, you’re supposed to be the hunter, not the hunted!

Key Points:

• Unsanitized user input in phpFox allowed for a PHP object injection vulnerability.

• Remote, unauthenticated attackers could exploit this vulnerability to execute arbitrary PHP code.

• Vendor initially dismissed the vulnerability until confronted with undeniable proof.

• Subsequent update (4.8.14) resolved the issue.

• The vulnerability, discovered by Egidio Romano, is now officially tagged as CVE-2023-46817.

The Back Channel:

"The Fox in The Hen House:"

In an audacious display of cyber ineptitude, phpFox was found to be susceptible to PHP object injection. A flaw in the software's /core/redirect route meant that unsanitized user input was being used in the unserialize() PHP function. In layman's terms, it's like leaving your front door wide open while you're on vacation and coming home surprised to find your house ransacked.

"The Puppet Masters:"

This vulnerability gave remote, unauthenticated attackers the ability to inject arbitrary PHP objects into the application scope. Basically, they could pull the strings and make the software dance like a clumsy puppet. The potential for mischief was extensive, with the opportunity to execute arbitrary PHP code being a significant concern.

"The Fox's Denial:"

When initially contacted about the issue, the vendor responded with a dismissive, "we currently do not have such security requirements". I guess that's one way to make a vulnerability disappear, just deny its existence!

"The Fox's Redemption:"

Fortunately, the vendor eventually realized the seriousness of the situation and released an update (version 4.8.14) that fixed the vulnerability. The vulnerability is now known as CVE-2023-46817, a charming little moniker to forever remind phpFox of its brief stint as a cyber punching bag.

"The Fox's Lesson:"

This incident serves as a reminder that no software is invincible, and that ensuring the security of user input should be a top priority. It's a wild cyber jungle out there, and even the Fox can get outfoxed. When it comes to cyber security, the hunter can quickly become the hunted.
