CVE-2020-25663 | 2020-12-08T21:15:12.420 | A call to ConformPixelInfo() in the SetImageAlphaChannel() routine of /MagickCore/channel.c caused a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed() or GetPixelBlue() was called. This could occur if an attacker is able to submit a malicious image file to be processed by ImageMagick and could lead to denial of service. It likely would not lead to anything further because the memory is used as pixel data and not e.g. a function pointer. This flaw affects ImageMagick versions prior to 7.0.9-0. | {

I have observed that it is possible to upload php file on the system through `manage files` functionality which leads to compromise the system. As I'm able to upload malicious php file with `.phar` extension, and able to execute php code on the server.
# Observation
On line 44-45 of `files.php`, I observed that the application uses blacklist extensions to restrict the php malicious file which can be easily bypassed with `.phar` extension.
# Steps to Reproduce
1) Login into the application's admin panel.
2) Navigate to the `http://<server>/admin.php?action=files`.
3) Now upload the php file with `.phar` extension, for e.g. `info.phar`.
4) After uploading the php file, navigate to the `http://<server>/files/info.phar`.
# Mitigation
* Rename the uploaded files to some random filenames, remove the file extension and then append your allowed file extension.
* Whitelisted extension approach should be applied instead of blacklisting.
* Correct use of `.htaccess` should be applied as shown below for preventing the php file execution in upload directory.
```
php_flag engine off
```

This issue affects multitenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.
An attacker that is able to create a ClusterIP service and set the spec.externalIPs field can intercept traffic to that IP. An attacker that is able to patch the status (which is considered a privileged operation and should not typically be granted to users) of a LoadBalancer service can set the status.loadBalancer.ingress.ip to similar effect.
This issue is a design flaw that cannot be mitigated without user-facing changes.
### Affected Components and Configurations
All Kubernetes versions are affected. Multi-tenant clusters that grant tenants the ability to create and update services and pods are most vulnerable.
### Mitigations
There is no patch for this issue, and it can currently only be mitigated by restricting access to the vulnerable features. Because an in-tree fix would require a breaking change, we will open a conversation about a longer-term fix or built-in mitigation after the embargo is lifted
To restrict the use of external IPs we are providing an admission webhook container: k8s.gcr.io/multitenancy/externalip-webhook:v1.0.0. The source code and deployment instructions are published at https://github.com/kubernetes-sigs/externalip-webhook.
Alternatively, external IPs can be restricted using [OPA Gatekeeper](https://github.com/open-policy-agent/gatekeeper). A sample ConstraintTemplate and Constraint can be found here: https://github.com/open-policy-agent/gatekeeper-library/tree/master/library/general/externalip.
No mitigations are provided for LoadBalancer IPs since we do not recommend granting users *patch service/status* permission. If LoadBalancer IP restrictions are required, the approach for the external IP mitigations can be copied.
### Detection
ExternalIP services are not widely used, so we recommend manually auditing any external IP usage. Users should not patch service status, so audit events for patch service status requests authenticated to a user may be suspicious.
If you find evidence that this vulnerability has been exploited, please contact security@kubernetes.io

There is a loop as below:
`
pps->num_tile_columns = 1 + gf_bs_read_ue_log(bs, "num_tile_columns_minus1");
pps->num_tile_rows = 1 + gf_bs_read_ue_log(bs, "num_tile_rows_minus1");
pps->uniform_spacing_flag = gf_bs_read_int_log(bs, 1, "uniform_spacing_flag");

pps->column_width[i] = 1 + gf_bs_read_ue_log_idx(bs, "column_width_minus1", i);
}
`
However, with crafted file, **pps->num_tile_columns** may be larger than sizeof(pps->column_width), which results a heap overflow in the loop.

pps_id may be a negative number, so will not return.

More than, because of the `pps->id = pps_id`, the vuln may lead to an any addr write.

] | Stored XSS vulnerability in Version 2.0 which allows remote attacker to inject arbitrary script or html. This being stored, will impact all users who have permissions to view the vulnerable page.
Vulnerable Endpoint: http://localhost/RemoteClinic/medicines
Step to Reproduce:
1) Login in Application as Doctor.
2) When you scroll down the main dashboard page, there is medicines options, Click "New Medicine".
3) Here is a "Medicine Name" Field which is vulnerable to XSS. Inject XSS Payload:
4) You can see there is client side validation on Medicine Name with maxlength is 30 but not validate on server side.
5) Change maxlength to 100.
6) Now Click on Register.
7) XSS Executed on medicines/new.php
8) Now go to /medicines, Click on Show All.
9) XSS Executed on /medicines.

] | LibreDWG "read_system_page" function heap overflow vulnerability
Description:
There is a heap overflow bug in "read_system_page" function at libredwg-0.10.1/src/decode_r2007.c:666:5
An attacker can exploit this bug to cause a Denial of Service (DoS) by submitting a dwg file.
This bug is caused by the following dangerous memcpy calling in read_system_page function: line 666
if (size_comp < size_uncomp)
error = decompress_r2007 (data, size_uncomp, pedata, MIN (pedata_size, size_comp));
else
memcpy (data, pedata, size_uncomp);
free (pedata);
We used AddressSanitizer instrumented in LibreDWG and triggered this bug, the asan output as follows:

We ensured there is a heap overflow vulnerability because of the dangerous using of memcpy function, attacker can use this bug to finish a DoS attack.
You can reproduce this heap overflow vulnerability by the follow step:

# vulnerability description:
In src/jsiObj.c:428, `len` is the length of the Array, and the PoC is initially set to a maximum value by o.length. After the calculation of the code, nsiz is calculated as a negative number, which can bypass the two checks of line 421 and line 425.
`obj-> arr` will get a smaller size of heap space, and then memset assigns a value to the space pointed to by `obj-> arr + obj-> arrMaxSize`, but this time has exceeded the actual heap range of ` obj-> arr`, causing heap overflow . | integer overflow and buffer overflow | https://api.github.com/repos/pcmacdon/jsish/issues/5/comments | 1 | 2020-04-13T14:03:30Z | 2020-04-14T00:10:53Z | https://github.com/pcmacdon/jsish/issues/5 | 598,907,622 | 5 |

The vulnerability code is in line src / jsiArray.c + 414, the function `jsi_ArrayMapCmd`, the vulnerability code is as follows:
The `curlen` here is also the size of the array, and can be arbitrarily set in the js code, for example in the poc
The affected code is in the analytic function `Jsi_ObjSetLength`, as shown in the figure:
The actual array size len is larger than `obj-> arrMaxSize`, which triggers the assert.
