The December 31, 2012 article titled “Google, Paypal, Facebook Internal IP disclosure vulnerability” reported several different kinds of information disclosure—not one shared vulnerability or a single confirmed attack. It described internal network addresses and server details, a Facebook session-cookie-related observation, and filesystem paths associated with Google material. The report does not establish that any of these examples remain exposed or exploitable today.
What the 2012 article reported
The Hacker News published the report on December 31, 2012, crediting it to Anonymous. Its examples and technical claims should be understood as claims made in that secondary report, not as independently verified findings. The article grouped unlike disclosures under one headline:
- Facebook: The report described an internal IPv4 address and a session-cookie-related observation. It did not establish that the observation enabled account access or that it remains possible. The historical administrative URL is not reproduced here.
- PayPal: The article said internal IPv4 range information and server details were exposed through subdomains, with examples associated with PayPal and Where.com.
- Google: Under the label “Server Path Disclosure,” the article described filesystem paths and package information visible in cached material related to Google downloads and products.
- NASA and Tata Consultancy Services (TCS): The report also mentioned an internal IP/subnet disclosure in a NASA file and a similar issue at TCS. It said the TCS issue had been fixed, but did not provide independently confirmed remediation evidence.
These are distinct data types and contexts. The report does not establish a common cause, a single vulnerability identifier, or a coordinated campaign linking the organizations.
Why internal addresses and infrastructure details can matter
An internal address or server detail can give an outside observer clues about an organization’s network or infrastructure. Such information may be useful during reconnaissance, especially when combined with other evidence. But disclosure alone does not show that an attacker can reach an internal system, bypass access controls, or compromise an account.

The 2012 article raised the possibility that the details could assist further attacks; it did not demonstrate that follow-on attacks occurred. An internal IP address is not automatically a critical vulnerability. Its significance depends on what was exposed, where it was accessible, what other security controls applied, and whether an attacker could use it to gain a meaningful capability.

The article is a historical account, not a current security advisory. It does not establish present-day exposure, exploitability, or remediation status for Facebook, PayPal, Google, NASA, or TCS. Nor does the reviewed report independently validate the examples or document successful exploitation. Its statement that TCS had fixed a similar issue remains a claim in that report, not independently confirmed remediation evidence.
For the original account and its wording, see The Hacker News report published December 31, 2012. It should not be treated as a current testing target or evidence of a live weakness.
