A List of Vulnerable Products to the Log4j Vulnerability
Details on What Vendor Products Are Impacted by This Flaw.
Two days ago, we wrote a post about the Log4j vulnerability that is currently wreaking havoc on the cyberthreat landscape. The flaw stands for an open-source Java logging library. By exploiting this vulnerability present in software apps and services worldwide, being part of the Apache Logging Service, hackers can perform remote code execution attacks (RCE).
What Is Log4j and How Has It Been Addressed?
The Log4Shell vulnerability is a JNDI injection exploit. The JNDI API provides discovery and lookup of resources by name and returns the result in the form of serialized Java objects. JNDI provides a Service Provider Interface (SPI) for flexible implementation of the backend naming and directory service protocols. To select the service provider, JNDI follows a URI format allowing provider and name to be specified during the request. (…) Exploiting the Remote Command Execution (RCE) is not as seamless compared to many known RCE that allow shell code to be injected directly into HTTP requests. An attacker will need to trigger log4j to query a remote service, which in turn will need to return the location of a malicious Java object that will result in command execution upon deserialization.
Following the exploitation of this vulnerability dubbed for the moment CVE-2021-44228, Apache released an emergency security update, the Log4j 2.15.0. The flaw can be also found under the names: Log4Shell or LogJam.
CISA Releases Guidance on Log4j Vulnerability
Jen Easterly, the CISA director, declared on Saturday’s statement that the agency is collaborating with private and public sector partners to find a solution for this issue.
We are taking urgent action to drive mitigation of this vulnerability and detect any associated threat activity. We have added this vulnerability to our catalog of known exploited vulnerabilities, which compels federal civilian agencies — and signals to non-federal partners — to urgently patch or remediate this vulnerability
Following this declaration, CISA released yesterday guidance on this matter. According to the agency, companies should immediately implement and prioritize the running of the available patches to address the Log4j vulnerability. Besides, if they cannot apply the patch, another method would be to set the log4j2.formatMsgNoLookups to true. This can be done by adding the string Dlog4j2.formatMsgNoLookups=True to the Java Virtual Machine command. It seems that this mitigation measure works only for 2.10 versions and later.
Vendors Advisories on Log4j Vulnerability
After the data about this vulnerability became public, vendors began an investigation to see if and which of their products are vulnerable. According to BleepingComputer, here is the list along with advice from every company:
Adobe identified that the product that is impacted by Log4Shell is ColdFusion 2021. In this sense, the company released on the 14th of December a security update. They also informed about a workaround in case if the patching of this flaw cannot be done.
What did Amazon was to update various products with a non-vulnerable Log4j version. Affected services, in this case, are OpenSearch, AWS Glue, S3, CloudFront, AWS Greengrass, and API Gateway for which the company published some updates here.
According to the company, no on-premise products are vulnerable when speaking of their default configuration. However, what may cause the risk or remote code execution in products like Jira Server & Data Center, Confluence Server & Data Center, Bamboo Server & Data Center, Crowd Server & Data Center, Fisheye, and Crucible is if the default logging configuration is modified and then the JMS Appender activated.
Many Symantec products impacted by this flaw were addressed by Broadcom, as the company published articles with knowledgebase and mitigations in this sense.
A list of Cisco products impacted by Log4j has been released by the company. You can find it here. Along with this list, it also published a calendar that indicated that some of the products will be patched starting yesterday.
