Although the offending dependency appears in all above artifacts, it is only the direct dependent of "dcae-analytics-model". All other uses are transient dependencies through this artifact. Hence the analysis below applies to the "dcae-analytics-model" artifact.

Vulnerability report:

False Positive Classification Reasoning

There is no use of BeanDeserializerFactory class in artifact "dcae-analytics-model". Hence we believe that this vulnerability report is a false positive.

Vulnerable artifacts:

<same as jackson-databind 2.4.4 above>

False Positive Classification Reasoning

There is no use of either UTF8StreamJsonParser or ReaderBasedJsonParser class in artifact "dcae-analytics-model". Hence we believe that this vulnerability report is a false positive.

Vulnerable artifact:

False Positive Classification Reasoning

According to these description, and the fact that the org.onap.dcaegen2.platform:inventory-api code does not enable use of global type information, using Class name as the type id, we believe that this report is a false positive.

Vulnerable artifact:

Dependency com.fasterxml.jackson.core:jackson-databind:jar:2.8.11 located at Module org.onap.dcaegen2.collectors.ves:VESCollector:jar

Vulnerability report:

CVE-2017-7525 originally reports that the application is vulnerable by using this component, when default typing is enabled. More details about the vulnerability is provided by https://github.com/FasterXML/jackson-docs/wiki/JacksonPolymorphicDeserialization.

False Positive Classification Reasoning:

The org.onap.dcaegen2.collectors.ves:VESCollector code does not enable use of global type information, using Class name as the type id. More over, VESCollector invokes json-schema-validator, which is where jackson-databind is used, post event  serialization primarily for schema validation. Thus, we believe that the reported vulnerability is a false positive.

Vulnerable artifact:

Vulnerability report: incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.

False Positive Classification Reasoning:

In mapper, Jackson is only used for converting between POJO to JSON, not the other direction which is reported as vunerable by CVE-2018-7489. The member call used is ObjectMapper.writeValueAsString. not the risky readValue method. Thus we believe the reporting is a false positive.

Vulnerable artifact:

Dependency org.springframework:spring-expression:jar:5.0.4.RELEASE located at Module org.onap.dcaegen2.services.mapper.vesadapter:snmpmapper:jar:0.0.1

Vulnerability report:

older unsupported versions, allow applications to expose STOMP over WebSocket endpoints with a simple, in-memory STOMP broker through the spring-messaging module. A malicious user (or attacker) can craft a message to the broker that can lead to a remote code execution attack.

False Positive Classification Reasoning:

In mapper, there is no use of STOMP over websocket. There fore we believe that this is a false positive.

Vulnerable artifact:

Dependency com.fasterxml.jackson.core:jackson-databind:jar:2.9.5 located at Module org.onap.dcaegen2.services.mapper.vesadapter:UniversalVesAdapter:jar:0.0.1

Vulnerability report:

jackson-databind is vulnerable to Remote Code Execution (RCE). A remote attacker can exploit this by uploading a malicious serialized object that will result in RCE if the application attempts to deserialize it.

False Positive Classification Reasoning:

In mapper, Jackson is only used for converting between POJO to JSON, not the other direction which is reported as vunerable by CVE-2018-7489. The member call used is ObjectMapper.writeValueAsString. not the risky readValue method. Thus we believe the reporting is a false positive.

Vulnerable artifact:

Dependency org.springframework:spring-webmvc:jar:5.0.4.RELEASE located at Module org.onap.dcaegen2.services.mapper.vesadapter:snmpmapper:jar:0.0.1

Vulnerability report:

older unsupported versions, allow applications to configure Spring MVC to serve static resources (e.g. CSS, JS, images). When static resources are served from a file system on Windows (as opposed to the classpath, or the ServletContext), a malicious user can send a request using a specially crafted URL that can lead a directory traversal attack.

False Positive Classification Reasoning:

The identified vulnerability exists when serving static artifact from Windows host. Our use is neither from a Windows host, or serving static file. Therefore we believe this is afalse positive.

incomplete fix for the CVE-2017-7525 deserialization flaw

FasterXML 2.9.5 released March 2018, supposed to correct this behavior (in tests currently).

After FasterXML upgrade to 2.9.5, we still have negative CLM scan results, we will be constantly looking at newer FasterXML version, providing permanent correction of bugs found in 2.9.x.
