Actively exploited vulnerability

Oracle Fusion Middleware: vulnerability flaw under attack

CVE-2012-3152 · Oracle Fusion Middleware Unspecified Vulnerability

Business software9.1 critical

What is affected

Oracle Fusion Middleware is mostly run by companies, schools and public bodies, not on home computers. You are unlikely to have it yourself, but organisations that hold your data may. Breaches that start with flaws like this one are how personal data ends up leaked.

Oracle Fusion Middleware Reports Developer contains an unspecified vulnerability that allows remote attackers to affect confidentiality and integrity of affected systems.

CISA's description

What an attacker can do

This is a vulnerability flaw. It lets an attacker misuse the product in a way its maker did not intend. CISA lists it because attackers are confirmed to be using it against real systems.

How it is reached
Over the internet or network
Access the attacker needs
No account needed
Does the victim have to do something?
No, works without the victim doing anything

What to do

  1. At home: nothing to install. Keep your own devices updated and use a different password for every service, so that a breach at one organisation does not open your other accounts.
  2. If you administer Oracle Fusion Middleware at work: apply the vendor's fix or mitigation now and review logs for signs of compromise, because the flaw was being exploited before it was listed.
  3. If the product is past its support date and no fix exists, take it off the internet or retire it.

Apply updates per vendor instructions.

Action required by CISA for US federal agencies

How urgent is it

CISA added this vulnerability to its Known Exploited Vulnerabilities catalogue on November 3, 2021, which means there is reliable evidence of attacks in the wild. US federal agencies must fix it by May 3, 2022, a deadline that has already passed. That deadline does not bind anyone else, but it shows how seriously the agency rates it.

The EPSS model estimates a 99% probability that this flaw will be exploited somewhere in the next 30 days. That is higher than 99.9% of all scored vulnerabilities.

Its CVSS severity score is 9.1 out of 10 (critical), as recorded in the US National Vulnerability Database.

Technical description

Unspecified vulnerability in the Oracle Reports Developer component in Oracle Fusion Middleware 11.1.1.4, 11.1.1.6, and 11.1.2.0 allows remote attackers to affect confidentiality and integrity via unknown vectors related to Report Server Component. NOTE: the previous information is from the October 2012 CPU. Oracle has not commented on claims from the original researcher that the URLPARAMETER functionality allows remote attackers to read and upload arbitrary files to reports/rwservlet, and that this issue occurs in earlier versions. NOTE: this can be leveraged with CVE-2012-3153 to execute arbitrary code by uploading a .jsp file.
