CVEAffectedPublishedCVSS v3CVSS v2
<= 2.1.125 MEDIUM

ejabberd before 2.1.13 does not enforce the starttls_required setting when compression is used, which causes clients to establish connections without encryption.

= 2.1.9, = 2.1.7, = 2.0.5, = 2.1.10, = 0.9.1, = 2.1.11, = 2.0.3, = 1.1.1.1, = 1.1.2, = 2.1.0, = 2.0.4, = 0.9.8, = 0.9, = 2.1.6, = 2.1.5, = 2.0.0, = 1.1.14, = 2.1.8, = 2.1.4, = 2.1.2, = 2.0.1_2, = 1.1.1, = 1.0.0, <= 2.1.12, = 2.1.3, = 1.1.0, = 1.1.3, = 2.1.1, = 2.0.2, = 1.1.1.04.3 MEDIUM

The TLS driver in ejabberd before 2.1.12 supports (1) SSLv2 and (2) weak SSL ciphers, which makes it easier for remote attackers to obtain sensitive information via a brute-force attack.

= 3.0.0, = 2.1.84 MEDIUM

The mod_pubsub module (mod_pubsub.erl) in ejabberd 2.1.8 and 3.0.0-alpha-3 allows remote authenticated users to cause a denial of service (infinite loop) via a stanza with a publish tag that lacks a node attribute.

= 3.0.0, = 2.0.5, <= 2.1.6, = 0.9.1, = 2.0.3, = 1.1.1.1, = 1.1.2, = 0.9.8, = 2.0.4, = 1.1.0, = 1.1.1, = 1.1.14, = 2.1.2, = 2.1.1, = 1.1.1.0, = 2.0.0, = 2.1.0, = 1.0.0, = 0.9, = 1.1.3, = 2.1.5, = 2.0.2, = 2.0.1_2, = 2.1.3, = 2.1.45 MEDIUM

expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

= 2.0.5, = 0.9.1, = 2.0.3, = 1.1.1.1, = 1.1.2, = 0.9.8, = 1.1.14, = 2.0.0, = 2.0.2, = 2.0.1_2, = 2.1.1, = 1.1.1.0, <= 2.1.2, = 2.1.0, = 1.0.0, = 0.9, = 1.1.3, = 2.0.4, = 1.1.0, = 1.1.15 MEDIUM

ejabberd_c2s.erl in ejabberd before 2.1.3 allows remote attackers to cause a denial of service (daemon crash) via a large number of c2s (aka client2server) messages that trigger a queue overload.

= 0.9.1, = 1.1.1.1, = 1.1.2, = 0.9.8, = 1.1.14, = 2.0.0, = 1.1.0, = 2.0.1_2, = 1.0.0, = 0.9, = 1.1.1, = 2.0.2, = 1.1.1.0, = 1.1.3, <= 2.0.34.3 MEDIUM

Cross-site scripting (XSS) vulnerability in ejabberd before 2.0.4 allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to links and MUC logs.

= 0.9.1, = 1.1.2, = 0.9.8, = 1.1.0, = 1.1.1, = 0.9, = 1.0.010 HIGH

Unspecified vulnerability in the mod_roster_odbc module in ejabberd before 1.1.3 has unknown impact and attack vectors.

<= 1.1.1.1, = 1.1.1.02.1 LOW

A third-party installer generation tool, possibly BitRock InstallBuilder, as used in products including Process-one ejabberd 1.1.1_1 and earlier, generates an installer that allows local users to cause a denial of service via a symlink attack on the bitrock_installer.log temporary file. NOTE: it is possible that this vulnerability is present in other products that use this installer.
