What it is: CVE-2018-1183 is a critical vulnerability in Dell EMC Unisphere for VMAX Virtual Appliance, Dell EMC Solutions Enabler Virtual Appliance, Dell EMC VASA Provider Virtual Appliance, Dell EMC SMIS, Dell EMC VMAX Embedded Management (eManagement), Dell EMC VNX2 Operating Environment (OE) for File, Dell EMC VNX2 Operating Environment (OE) for Block, Dell EMC VNX1 Operating Environment (OE) for File, Dell EMC VNX1 Operating Environment (OE) for Block, Dell EMC VNXe3200 Operating Environment (OE), Dell EMC VNXe1600 Operating Environment (OE), Dell EMC VNXe 3100/3150/3300 Operating Environment (OE), Dell EMC ViPR SRM, Dell EMC ViPR SRM, Dell EMC XtremIO, Dell EMC VMAX eNAS, Dell EMC Unity Operating Environment (OE), published on 30 Apr 2018. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2018-1183 in the wild and no public exploit code. Affected product: Dell EMC Unisphere for VMAX Virtual Appliance, Dell EMC Solutions Enabler Virtual Appliance, Dell EMC VASA Provider Virtual Appliance, Dell EMC SMIS, Dell EMC VMAX Embedded Management (eManagement), Dell EMC VNX2 Operating Environment (OE) for File, Dell EMC VNX2 Operating Environment (OE) for Block, Dell EMC VNX1 Operating Environment (OE) for File, Dell EMC VNX1 Operating Environment (OE) for Block, Dell EMC VNXe3200 Operating Environment (OE), Dell EMC VNXe1600 Operating Environment (OE), Dell EMC VNXe 3100/3150/3300 Operating Environment (OE), Dell EMC ViPR SRM, Dell EMC ViPR SRM, Dell EMC XtremIO, Dell EMC VMAX eNAS, Dell EMC Unity Operating Environment (OE). No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
