`CVE-2017-3252`

5.8 Medium Protected by RASP

Description

Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JAAS). Supported versions that are affected are Java SE: 6u131, 7u121 and 8u112; Java SE Embedded: 8u111; JRockit: R28.3.12. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, JRockit, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded, JRockit accessible data. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS v3.0 Base Score 5.8 (Integrity impacts).

        Description:
            It was discovered that the LdapLoginModule class in the Java
            Authentication and Authorization Service (JAAS) component of OpenJDK
            did not use a correct way to extract user DN from a result of the
            LDAP query used to locate user in an LDAP database.  A specially
            crafted user LDAP entry could cause the application to use
            incorrect DN.

# Rule Outcome Status Detail

identity: Does this identifier describe a vulnerability at all? first match wins

1 rejected no-match CVE Program withdrawal of this identifier

scope: Is the vulnerability ARMR's to address? first match wins

2 armr-patch-file decided it matched Protected by RASP ARMR patch file exists for this CVE

3 armr-secure-rule-file not-reached An ARMR security-rule template on disk for this CVE

4 manual-classification not-reached A researcher's recorded decision for this specific CVE

5 manual classification not-reached Manual classification of this CVE in the legacy dataset

6 non-java-upstream not-reached A root cause in non-Java code: an OS kernel, a C library, or a bundled runtime

7 oracle-component not-reached The defect being in a component of a tracked product the agent does not reach: JavaFX, the Java SE installer, the native WebLogic proxy plug-in. Oracle gives these no CPE of their own and names them only in the description.

8 osv-maven not-reached An OSV.dev record of this CVE affecting a package published to Maven Central

10 known-cpe-product not-reached An NVD CPE naming a product ARMR tracks

11 cna-cpe-product not-reached A CPE the CNA published naming a tracked product. Oracle publishes these on advisory day, months before NVD.

12 oracle-advisory-family not-reached A tracked product family named in Oracle's own risk matrix. CPE cannot carry a suite name, only a module.

20 below-action-threshold not-reached Medium or Low severity, no KEV listing, no PoC clearing the evidence bar, no CISA verdict, no Oracle advisory
