Security Bulletin: Public disclosed vulnerabilities from Jackson-databind affects IBM Spectrum LSF

Description

## Summary Public disclosed vulnerabilities from Jackson-databind affects IBM Spectrum LSF: CVE-2017-7525, CVE-2017-15095, CVE-2017-17485, CVE-2018-5968, CVE-2018-7489 ## Vulnerability Details CVE-2017-7525 Jackson-databind (Also implemented in JBoss BPM Suite) is vulnerable to remote code execution when deserializing via the `readValue()` method of `ObjectMapper`. CVE-2017-15095 An unauthenticated attacker can create a specially crafted payload that when deserialized in `Jackson-databind` can lead to Code Execution. CVE-2017-17485 Deserialization of untrusted user data in Jackson Databind could allow an attacker to perform PHP Object Injection resulting in Remote Code Execution. This issue exists because of an incomplete fix for CVE-2017-7525 which the vendor tried to address through an incomplete blocklist. CVE-2018-5968 FasterXML jackson-databind through 2.8.11 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 and CVE-2017-17485 deserialization flaws. This is exploitable via two different gadgets that bypass a blocklist. CVE-2018-7489 FasterXML jackson-databind contains a remote code execution (*RCE*) vulnerability due to an incomplete fix for the CVE-2017-7525 deserialization flaw. An unauthenticated attacker can exploit this vulnerability via `readValue` method to execute arbitrary code. ## Affected Products and Versions IBM Spectrum LSF 10.0.0.4 IBM Spectrum LSF 10.0.0.5 IBM Spectrum LSF 10.0.0.6 IBM Spectrum LSF 10.0.0.7 ## Remediation/Fixes **Product** | **VRMF** | **APAR** | **Remediation / First Fix** ---|---|---|--- LSF | 10.1.0.4 | None | See fix below LSF | 10.1.0.5 | None | See fix below LSF | 10.1.0.6 | None | See fix below LSF | 10.1.0.7 | None | See fix below Download Fix 512358 from the following location: [http://www.ibm.com/support/fixcentral/swg/selectFixes?product=ibm/Other+software/IBM+Spectrum+LSF&release=All&platform=All&function=fixId&fixids=lsf-10.1-build512358&includeSupersedes=0](<http://www.ibm.com/support/fixcentral/swg/selectFixes?product=ibm/Other+software/IBM+Spectrum+LSF&release=All&platform=All&function=fixId&fixids=lsf-10.1-build512358&includeSupersedes=0>) 1) Go to the patch install directory: cd $LSF_ENVDIR/../10.1/install/ 2) Copy the patch file to the install directory $LSF_ENVDIR/../10.1/install/ 3) Run patchinstall: ./patchinstall <patch> 4) Run "badmin mbdrestart" ## Workarounds and Mitigations ##
