How the Exploit Works

An attacker exploits this vulnerability by sending a large volume of specially crafted messages to a target system running the vulnerable versions of Ericsson PCC. These messages can cause high resource consumption on the target system, leading to service degradation. If successfully exploited, this vulnerability could lead to system compromise and potential data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This pseudocode represents the sending of a large volume of crafted messages to the target.

for i in range(1,1000000):
POST /target_endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "message": "specially_crafted_message_" + str(i) }

Mitigation Guidance

Until a patch is released by the vendor, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can be configured to identify and block the large volume of crafted messages associated with this exploit. Once the vendor patch is available, it should be applied immediately to all affected systems to remediate this vulnerability.
