Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the version of the glusterfs packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A flaw was found in glusterfs which can lead to     privilege escalation on gluster server nodes. An     authenticated gluster client via TLS could use gluster     cli with --remote-host command to add it self to     trusted storage pool and perform privileged gluster     operations like adding other machines to trusted     storage pool, start, stop, and delete     volumes.(CVE-2018-10841)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2806 advisory.

  - glusterfs is vulnerable to privilege escalation on gluster server nodes. An authenticated gluster client     via TLS could use gluster cli with --remote-host command to add it self to trusted storage pool and     perform privileged gluster operations like adding other machines to trusted storage pool, start, stop, and     delete volumes. (CVE-2018-10841)

  - A privilege escalation flaw was found in gluster 3.x snapshot scheduler. Any gluster client allowed to     mount gluster volumes could also mount shared gluster storage volume and escalate privileges by scheduling     malicious cronjob via symlink. (CVE-2018-1088)

  - It was found that glusterfs server does not properly sanitize file paths in the trusted.io-stats-dump     extended attribute which is used by the debug/io-stats translator. Attacker can use this flaw to create     files and execute arbitrary code. To exploit this attacker would require sufficient access to modify the     extended attributes of files on a gluster volume. (CVE-2018-10904)

  - It was found that glusterfs server is vulnerable to multiple stack based buffer overflows due to functions     in server-rpc-fopc.c allocating fixed size buffers using 'alloca(3)'. An authenticated attacker could     exploit this by mounting a gluster volume and sending a string longer that the fixed buffer size to cause     crash or potential code execution. (CVE-2018-10907)

  - A flaw was found in the way dic_unserialize function of glusterfs does not handle negative key length     values. An attacker could use this flaw to read memory from other locations into the stored dict value.
    (CVE-2018-10911)

  - An information disclosure vulnerability was discovered in glusterfs server. An attacker could issue a     xattr request via glusterfs FUSE to determine the existence of any file. (CVE-2018-10913)

  - It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick     process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this     will result in a crash of multiple bricks and gluster volumes. (CVE-2018-10914)

  - It was found that the mknod call derived from mknod(2) can create files pointing to devices on a     glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read     data from any device attached to the glusterfs server node. (CVE-2018-10923)

  - A flaw was found in RPC request using gfs3_mknod_req supported by glusterfs server. An authenticated     attacker could use this flaw to write files to an arbitrary location via path traversal and execute     arbitrary code on a glusterfs server node. (CVE-2018-10926)

  - A flaw was found in RPC request using gfs3_lookup_req in glusterfs server. An authenticated attacker could     use this flaw to leak information and execute remote denial of service by crashing gluster brick process.
    (CVE-2018-10927)

  - A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink     destinations to point to file paths outside of the gluster volume. An authenticated attacker could use     this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on     glusterfs server nodes. (CVE-2018-10928)

  - A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could     use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.
    (CVE-2018-10929)

  - A flaw was found in RPC request using gfs3_rename_req in glusterfs server. An authenticated attacker could     use this flaw to write to a destination outside the gluster volume. (CVE-2018-10930)

  - The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the     'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr'     function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of     service. (CVE-2018-14652)

  - The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in     the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker     could exploit this to cause a denial of service or other potential unspecified impact. (CVE-2018-14653)

  - The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' translator. A     remote attacker with access to mount volumes could exploit this via the 'GF_XATTROP_ENTRY_IN_KEY' xattrop     to create arbitrary, empty files on the target server. (CVE-2018-14654)

  - The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via     use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by     mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an     arbitrary number of files in the server's runtime directory. (CVE-2018-14659)

  - A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of     GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for     single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node.
    (CVE-2018-14660)

  - It was found that usage of snprintf function in feature/locks translator of glusterfs server 3.8.4, as     shipped with Red Hat Gluster Storage, was vulnerable to a format string attack. A remote, authenticated     attacker could use this flaw to cause remote denial of service. (CVE-2018-14661)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:1954 advisory.

    GlusterFS is a key building block of Red Hat Gluster Storage. It is based     on a stackable user-space design and can deliver exceptional performance     for diverse workloads. GlusterFS aggregates various storage servers over     network interconnections into one large, parallel network file system.

    Security Fix:

    * glusterfs: access trusted peer group via remote-host command     (CVE-2018-10841)
